Marine Mechanic and Boat Tune-Up in San Diego

Q: What's included in a tune-up?

Preventive service for your engine: oil and filter change, impeller check or replacement and an inspection of the parts that wear with use. The exact list follows your engine's manual.

Q: Do you service my engine brand?

Tell us the make and model when you request service. We confirm coverage before scheduling.

Q: Do I need to haul out my boat?

Tune-ups, oil changes and most repairs are done at your slip. If a job requires a haul-out, you'll know before we start.

Q: How often should I service my engine?

Follow your engine manufacturer's recommendations, usually based on engine hours and time. We schedule your service around those intervals.

Q: Do you also clean the hull?

Yes. Hull cleaning, Top Wash, Wax and Detail and Cabin Cleaning are done by the same team.

An engine that won't start ends the day before it begins. We keep yours on a maintenance schedule and fix what goes wrong, right at your slip.

Justin Time Diving has helped keep the bottoms of our 10 racing sailboats in great condition. Not only does Gustavo come clean right before a race but also helps with post race inspections. The attention to detail is unmatched to other services!
Paul Crownover
These guys are great! I’ve been using them for the last couple of years on our rental fleet and they do a stellar job! Reliable, punctual, and professional. 10/10 would definitely recommend.

Justin is very conscientious and detail orientated. We dry sail our 52 foot boat San Diego and are able to continually inspect his work out of the water. It always looks good as new. Thanks very much!
Rene' Roques
Wow, great service! Personable, on time, fairly priced, knowledgeable and has a can-do attitude. Looking forward to using them again
Kayla McDaniel
Gus was our diver for a few months prior to selling our late father's sailboat. He was the most reliable diver we've worked with this year. His services were fairly priced, he was very communicative and reliable. He was always quick to get back to me whenever I reached out to him. He shared photos with us after the initial cleaning. Really pleasant experience working with Gus. I'd recommend Justin Time Diving to anyone looking for a reliable diver who does good work and a good rate.

We have been using Justin for 2 years now. We are so impressed with his work and customer service! Not only does he clean our hul and replace our zincs, he details our boat once a year and it is flawless! Great work, and great prices! We highly highly recommend him! Thanks Justin!!!

Ed Badrak
Justin has service my boat for well over four years. The integrity and ethics that he demonstrated while taking care of my boat is beyond reproach. He kept me informed about the condition of the bottom of my boat. He always advised me on the season's planned maintenance schedule. I highly recommend this individual to anyone looking for a person who will care and love their boat as you do. A true professional
chuck harris
Justin unlike a number of boat divers knows how to take care of your boat. He doesn't try and have you replace items such as zinc before it's time. He is willing and able to do multiple things on your boat or will give you the name of the right person. Knowing Justin for a number of years and having work on my boat I would highly recommend him.
Marc B
So I've known Justin for several years now, and he's taking excellent care of my boat! He's a very experienced diver and knows exactly what he's doing and how to take great care of boats. I highly recommend his services. And one of his most important attributes is he's conscientious and takes care of what needs to be done with no nonsense. You can definitely count on him and the work that he does is always perfect.

I'm the owner of a 42' Eggharbor Sport Fishing Yacht. Justin has been servicing my boat the past 3 years now since we had the bottom painted. Recently found out the bottom has an extra 2-3 years before repainting again. Typically I am repainting every 5 years because of how much use we have, or maybe that our last diver was doing the wrong job, possibly no job... He has saved me a BOAT load of money by the quality work that he is doing. Also best price for metals. Highly recommend!
Rich Zbinden
Justin Time Diving is hands down the best. Justin is extremely professional always on schedule with our appointments, does nothing but the highest quality work. I will refer him to any of my friends, family, or someone just looking for a cleaning!
