Outstanding service! Dennis and his team completely rebuilt my MerCruiser 350 Mag. The attention to detail was incredible - they even painted the engine bay while they had everything apart. My 32' Sea Ray runs better than when it was new. These guys know their stuff and stand behind their work. Highly recommend for any serious boat owner.

Professional and reliable service every time. I've been bringing my Volvo Penta D4 here for 3 years now. They always explain what needs to be done, provide fair estimates, and complete work on time. The location is super convenient for dropping off my boat. Dennis personally oversees every job - that level of owner involvement is rare these days.

Been fishing San Diego waters for 20 years and these guys are the ONLY ones I trust with my tournament boat. They've done everything from emergency repairs before big tournaments to complete sterndrive overhauls. Fast, reliable, and they understand that downtime costs money. Worth every penny!

Excellent experience from start to finish. My boat's electrical system was a nightmare - previous shop couldn't figure it out. Dennis diagnosed the problem in 30 minutes and had it fixed the same day. Fair pricing, honest communication, and quality work. Finally found a marine shop I can trust!

Dennis Allen's shop is the real deal. Been in business since '86 and it shows in their expertise. They worked on my twin Volvo Penta setup - complete fuel system cleaning and injector service. Boat runs like a dream now. These guys eat, sleep, and breathe marine engines. Couldn't be happier!

As a female boat owner, I really appreciate how Dennis and his team treat me with respect and explain everything clearly without talking down to me. They've done several jobs on my boat and always deliver quality work at fair prices. The shop is clean, organized, and professional. Highly recommend!
