Had my throttle cable replaced. Didnt tighten down the lockdown bolt. Almost ran people over when trying to beach my boat because I put in reverse and took off forward. Adam said it wasnt them it was my gear box. Fixed it myself.Never went back again

Great mechanic They really know their stuff and will go the distance to get it done

Yea boats cost arms legs and retirements but they can fix it here. Still cost the same but do it once do it right. Very helpfull. Worth the time, drive, and wait.

I lost oil pressure thought I lost my $40.k Motor. It was just the pressure sensor. So I had the whole boat and trailer serviced. Due to COVID the Merc parts were slow coming in not the fault. I guess they got caught up in the Corona Virus. Ha! Good Work Guys Thx.

This shop is awsome

Joe know s his boats! Great shop, and he can hook you up with boating safety classes!

DO NOT TAKE YOUR WATER TOYS HERE! Sketchy and unprofessional. No communication and didnt even finish the work they were supposed to do so I took my stuff back in pieces to get worked on by axxis motorsports instead.

Great service. their employees are very knowledgeable about all aspects of the boating world. The owner Joe is also a coast guard auxiliary officer, so you know their doing everything right. Theyve been providing excellent service for over 40 years, no small task in todays marketplace. Most repair facilities wont even work on boats 10 years or older. They not only have a vast array of parts but were able to find parts for discontinued motors and outdrives. They gave me a solid estimate for the work I needed done a at a more than competitive price. I see them every year for my scheduled maintenance and they never let me down. Great to see independent shops like this still exist with people that stand behind their work. A great experience every time!

ZERO STARS!!!!!!!DO NOT BRING YOUR BOAT HERE!They promised to have our boat repaired and ready to go by a specific date, we dropped it off over 1 week in advance. We called to check on the status and we were told that it would not be ready for another week. When we explained that Adam had promised to have our boat done on time and that we needed the boat as we were going out of town, they informed us that the part had not been ordered. He also told us that there were several other things wrong with the boat and that it was going to cost a crazy amount of money. We insisted that we needed the boat and that all extra work would be completed later, just get it running for our trip. We left 2 days late for our trip, they took everything out of all of the boats compartments and told us they didnt know where it went so we needed to put it all back. This place is a joke! Adam and all the employees are rude, they lie, and simply do not care about their customers.Dont waste your time!

They are disrespectful they dont care for nobody but their selves and Adam doesnt pay his employees but what I dont understand the employees are still working for him

Great customer service, excellent work My boat had not run in 5 yrs we have had full season with boat now running top condition service this year was clean with no issues they are great guys over there, Adam is Exceptional Tech.

Was sent to from Tillys Marine to inquire about a purchase of a New Volvo Penta 8.1 engine and when I arrived I wasnt given the light of day. I walked by some young guy with a goatie talking a customer outside, went in to the shops office and there was two lil kids on the cpu. Walked outside and leaned on a forklift waiting for this guy to finish up his conversation for about 20 min. After walked right passed them again and did not get any kind of acknowledgement I was there. Good thing I found Daves Marine in Chino and set up an appointment for tomorrow while I waited. Thanks hopefully I get a good deal.

I took my boat to Corona marine to get the fiber glass fixed. I hit a sand bar pretty hard and messed it up pretty bad. They took a look at it and said they could fix for a great price. I had them do the repair and i was amazed how it turned out. We cant tell where the repair was done because it flows perfectly. They did a great job and will use again. Thanks

WARNING! This place deserves no ratings after I was charged 900+ for 2 jet ski services. Spark plugs not included for 375 a ski really? Adam might want another $100 for an hour servise. Adam talks real sweet and very knowledgeable at taking your money. The owner is the old man that just drulls as you walk in after giving you a quote over the phone. He only talks when you are handing him MONEY. Check out yelp review most recent

Great shop very helpful staff Adam is very knowlegable really takes the time to explain why or what needs to be done. Other shops do not. There prices are good would highly recomend bringing your boat or jetski here.

My boat has never run better excellent boat shop good prices and great people Adam is wounderful and very helpful highly recomend.

Adam is a great guy there and has done good work for me over the years.

Adam service my boat in 3 days! Wow what a great job, just in time for my Colorado river trip.

Dont waste your money. I paid over $5k in work and boat still didnt run right and nothing was on time. Only come here if your desperate or local.

Place is a JOKE! Adam and joe are just ripping people off left and right! STAY AWAY FROM HERE!!! They will promise you everything charge you up the ass then do shaddy work if any at all. Workers here are careless ripping smashing scratching your investment!

The customer service and workmanship is horrible, non existent and a rip off. I would never take my boat back there for anything.

I puchased a used boat and advised corona marine was who did maintenance, I took the boat for annual service and a any repairs suggested/needed. I advise Adam gauges and radio not working and was advised service included a complete and thorough inspection of boat AND trailer of everything. Adam said need new prop the one I had was scratched and bent some. I agreed and was told that it would be ready in a week and anything was found that needed replacement or repair they will call and they did not. A message from Joe who is the owner that the boat was ready. Additional charge of $110 was put on (no call to authorize) for replacement of wiring for the lights that Joe said were not working on the boat (which are not working at all now). I asked if the gauges were now working and Joe told me he was sure they were but would double check since he was unaware there was any problem with the gauges (It was written on contract). It was the initial problem on the paperwork it was in fact written down by Adam. They in fact were not working on it as stated originally. Joe apologized and told me he would take care of it and it would be ready the following day. I called the following day and he advised me that the boat needed to be completely rewired it was a mess which would be approximately $600-$650 I agreed to and was told it would be ready in three or four days which would be on approximately July 3rd and now 3 weeks in shop. I chose to call on Thursday and confirm it would be ready on Monday the 3rd as promised by Joe, Adam told me that it had not even been started, it was going to be 4 to 5 days and they were closed on the Monday Joe promised it. I advised Joe I was unhappy with the runaround and unprofessionalism and would be picking up my boat and he said thats fine. Halfway to pick it up he phoned and said they were working on it right now I told him I did not want work done I wanted to pick it up and would speak to him when I arrived. When I walked into the building Adam stated its all done its ready, watch, it starts and they dry started it. I explained that starting it was never the problem it was the gauges and the radio and he replied Oh? I was shown the ignition they took out and replaced which was also never an issue nor approved. Joe was very adamant that if I was to give him the chance he could make the repairs and complete the job to my satisfaction. He advised me that the work would be completed by Saturday which this was on Thursday afternoon. I phoned on Saturday afternoon and spoke with Joe said it needed 10 more minutes of work, when could I be there to pick it up. Within 30 min to 1 hour and he said that would be fine. I returned for the third time, now he advised me that he only replaced the wiring that was bad he in fact did not replace all the wiring (this he claimed was necessary) but assured me that all the gauges are now working but that the radio was not working and that I could probably find a new one for about $50. I just wanted to get my boat out and be done. He charged me $1505 which incl 3% credit card fee took off the extra $110 he claimed he replaced the lights on the boat and are not working. Lights on the trailer still not working and when he went to replace and repair them he shorted out all of the lights and blew a fuse in my suburban, said he didnt have those kind of fuses. somehow located a 20 amp fuse that was 5 Amps higher than the one that was blown and the lights came back on, he undid wires advised me I need to have all the wiring replaced on the trailer the wiring was old and it should all be replaced. The back of the trailer in the middle light was not working, he said the bracket was worn out if he was to replace the light the bracket would break and I dont really need that light anyway since I have the other lights. Spent 45 min. while he fixed the lights and wiring, blown fuse, shouldve been done prior to pick up as promised. I did not receive what I was promised or paid for. Their word is worth zero. Dont trust them. I have contacted BBB

Good parts and accessories selection

Horrible service!

Very rude

Read the reviews on yelp.... terrible costumer service
