I'm incredibly happy I found H and M Marine. Before working with them, I used to handle my own boat maintenance or worse, take my boats to other shops that turned out to be total nightmares. My last experience before finding H and M was horrific; a faulty wiring job left me broken down and stranded. H and M completely turned that around. They not only fixed all the mistakes from the previous shop, but also installed a kicker motor and completed a long list of upgrades I'd been wanting for a while. Everything was done cleanly, efficiently, and with a high level of craftsmanship. Shane is a total badass. He's clearly an expert, and it shows in the quality of work he and his team deliver. I run a quality-oriented construction company myself, so I know what it takes to do a job right and I can confidently say H and M Marine is the real deal. I live in Martinez, and I'll gladly make the drive every time I need work done, no question. I'm already making a list of projects for the off-season. If you're looking for top-tier workmanship at a fair price from people who genuinely care about what they do, look no further. These guys are awesome.

Way overpriced for their parts and install. They have a set price for both. The Suzuki outboards are reasonably priced but they get you on items above.

First interaction with H&M was to purchase a new Yamaha outboard to repowered our Grady White. More boat work was done in addition to just hanging a new engine. The price for work completed was fair. Covid hit hard and I believe we were the last boat done before they temporarily closed. Ethan was very professional and did the best he could communicating with us during difficult times. I'll focus on recent major work I had done to install new electronics on a newer Grady I purchased. I had planned to install myself, but the project was a it more complicated and involved than I wanted to tackle. I had already purchased a new Garmin chartplotter/fishfinder and radar, along with new antennae's, mounts, and lights. I approached Shane, Ethan's partner, about installing what I had in addition to new Yamaha gauges, all new Yamaha wiring and network cables/components to make Command Link compatible, remove and replace new hydraulic steering lines, R&R helm, install new throttle and shift cables, install Starboard to replace damaged wood (one piece I had Tap Plastic custom fabricate using old piece as template). After initial agreement Shane came back saying he needed to charge a "corkage fee" because I did not purchase the all Garmin products from him. I apologized and explained they have already been purchased from West Marine. I have seen their install work and was impressed, so I paid the additional $500 fee. I found out about the retail pricing when I also purchased from H&M a Standard horizon VHF and another Garmin MFD , priced $100 and $500 more than WM. I also supplied the the LED deck and spreader lights, VHF antennas with mounts, radar pedestal, GPS antenna, VHF loudhailer, and I had a custom stainless navigation light mount fabricated. An estimated 2 weeks turned into 2 months. I get they have a yard packed with boats, and luckily I have another boat I used during that time almost daily. Boat is done. Custom flush mounted electronics are beautiful! Super clean wiring with wires neatly concealed in the radar arch. New MFD shows all engine functions. Love it. Total bill was over $11k. Ouch. That's not including what I purchased prior. Now the not so good. Picked up boat and launched 2 days later. Load gear at O dark thirty, go to start, nothing. Batteries seemed ok. Tilt and lights all ok. No crank. Bypass neutral start but check engine light and won't run above idle. I call H&M and tell them the issue. I am told the motor needs to be hooked up to shop computer and diagnostics done. I find internet instances where a low battery, not faulty, will cause the issue I am having. I relay info to H&M owner who replies he has never heard of such a thing in all his years of servicing. I ask him to throw it in a charger and see before dumping money into computer and replacing a TPS he thinks is the cause. I also question the neutral start switch as something they may have done since they replaced throttle and shift cables. "Impossible, we only changed the cables". A week later I get the call. Yes, surprisingly topping the batteries off worked. Never saw that before. Oh yeah, we fixed the NSS. No charge. (Later I get bill for over $400 for checking if code reoccurred) Good Very nice custom install of electronics. Wiring through arch very clean. Location Bad Did not top batteries. Suggest to top off if boat sits or extensive electrical work done. Cabin had debris like wood shavings, old caulk, and wire insulation strippings. Shop reply per email was, "it was better than it was." Really? Old radio bracket left mounted in cabin. Factory livewell switch was removed and replaced with new spreader light switch. Now how do I turn on baitwell pump? So far after 2 emails issue still Unresolved! Typical upsell. Hydraulic leak at SeaStar helm. Not hose or fittings. Owner recommended replace entire helm. I mention I've experienced this and has been steering shaft seal. Simple fix. He strongly suggested updating new hoses and if replaced steering shaft seal no guarantee. O-ring replacement worked to his surprise, and I was charged to remove old hydraulic lines and install new ones. I physically installed radar dome on the arch using a short pedestal. Owner and installer both said it didn't look right on it, and if I towed a lot better clearance without. Advised mounting it flush to arch, and the installer would purchase it for his hardtop on his own boat. Paid $120 new, sold for $50, and was charged a removal and reinstall fee. There's more, but I'll stop here. No marine mechanic is perfect. I have taken my boats to all of the major dealers in the Bay Area for the last 4 decades, and have had issues with all of them. Not just minor complaints, but straight up pay for Job and not fixed! I'd give H&M 3.5 stars if I could. I do love their install work, and looking at my every time I'm on the boat looking at my dash and using my new electronics makes me happy. Happiness just comes at a cost

I needed a new outboard for my boat. The old outboard was getting unreliable so looking for a new top notch reliable outboard. H&M provided me with a quote and I accepted it. Installation went smoothly. Has more power than before. Very professional and on time.

I first met the team when they moved to the current location some years ago. Since then I have had my boats serviced as well as having referred them numerous friends. They are knowledgeable and well staffed to handle your needs. Like boating, there is always something going on in service. I guess the highest compliment I can give these guys is that even when things are not as simple as first thought or the job required different work, they will work with you to make sure it is right. If it is routine service, a new boat, or a repower, I highly recommend the team @ H&M Hirschfeld & McCormack. Phil Havlicek Reel Time Charters, LLC
