Don’t let your engine over heat because of simple overlooked maintenance! on 4.2L Yamahas, the fuel cooler on the VST gets a ton of salt buildup. That leads to this, water passages totally blocked. This should be checked at least every other year if not annually! Preventative maintenance saves you time and money before things get worse.

This customer had trouble seeing his gauges and switches at night, he didn’t want to do a full custom panel yet so we installed these Lumitec Aurora red/white lights. No switch, they come on just by twisting the bezel. We also preformed a full service on his 300hp Etec. While completing the service we found one of the thermostats was missing a spring, and the removable water tube extension was cracked. Went through and made sure it was safe for the season, bilge and float were both inoperable, repaired wiring and replaced float. Now this guy is ready to rock and roll.

Took this 10ft inflatable tender from ordinary to insane! We did 4x 6.5” JL Audio M3, Single 10” JL M3 sub, Fusion RA70 head unit, wired full RGB control to a wireless remote. Lumitec SeaBlaze underwater lights wired to a backlit push button. Had to get creative with mounting the JL XDM700 Amplifier dealing with such a small space, but came out super clean mounting on underside of hatch. Not only did we tune it to sound great, everything we installed is now being fed by a main fuse panel and circuit breakers for everything. Have an audio system you want done right and really clean? Get in touch today

UH OH! That’s not gas! Someone accidentally filled this Grady-White with diesel instead of gas! Engine didn’t really like it. We flushed all the diesel out of the boat system and the engine systems. Replaced the plugs and filters, got some gas in it and it’s running perfect. Easy fix but first time in almost 7 years i’ve seen someone make this mistake!
