In speaking with my diver he mentioned cleaning a boat that had a low voltage line attached to its bronze thru hull, presumably to keep it free of critters. Thats a new one to me!

I need to replace the fresh water tank in my 390ec. Suggestions? Daytona Beach area.

Im not at the boat but i know the windlass is the original Good brand. I have a few hundred feet of rode with no chain. Anyone know if the Good can handle a chain combo? 1989 390EC

I'm not at the boat but I hope to have the part in hand when I get there so....any gas engine 390ec people know what the P/N or dimensions are for the trans cooler??

I'm pretty sure it has been addressed but I can't seem to find the posts. My rear ac no longer produces any heat. Forward unit works great. What needs to be done to fix?

Unit starts. Runs nice at 1800 and shows 60 Hz but 55 volts. I adjust the idle to 2040 to get 115 volts. A/C won't come on and genny sounds like its trying to bog down yet still runs at 2040. Thoughts? Governor oil changed, outlets show 115v. Even lights have hard time turning on.

If anyone happens to be near a 1989 7.4L Mercruiser I would appreciate if you could tell me the casting numbers on the cylinder heads. Thanks

Is there anyone here that can help with setting up a old datamarine multi? Can't figure out how to set the temp function.

Getting just enough water in #1 to make the motor stumble. Is there a way to determine if manifold is bad or intake gasket leaking. I pulled distributor and there is a small amount of milkshake oil in plenum but none on dipstick, even after motor warms up. I tend to go with intake gasket...

Seacock that is. At the boat 3 weeks ago. All good. Shut off the seacocks when I left. Got to boat today and flipped on the levers. Uh oh, for some reason one of the clear cylinders started pissing water, right at the seam. Sure glad I had a spare on board.

Just a fancy muffler? What can go wrong with them? I'm just trying to understand my equipment.

How do I remove the air horn on a 390ec?? Please don't say I have to remove the ceiling panel.

Wanting to get bottom painted but diver says i have a few blisters on hull. What to do???

Oil, that is. If i just putter around, no problem. If i run hard, offshore and back, i end up with at least a quart of oil under the port engine. Oil cooler? Leaky hose? Everything else looks good but its hard to find the origin because of the splashing that occurs when running. Inquiring minds...

Simrad ap14h. Is there a trick to getting this to work? Replaced hoses from pump to ram. Linear feedback is good. Apply power to pump and ram runs smoothly. Bled the system repeatedly. I can't get the controller to accept calibration. There is a pause after i hit the gain button and...

Thats the sound my vacuflush makes. Won't shut off unless i flip switch. Got vacuum at the bowl and flushes ok. What say you? Duckbills, pressure switch, or air leak?

390ec with 454's. can someone give me a quick run through on replacing the motor zincs?

I put a 14 ft, 9db Shakespeare on my Icom. No matter what i do i still pull in a bunch of noise and sound bad on Seatow auto radio check. Thinking...go back to 6db and just use the extension?

pros and cons on flipping a marine motor from a rocker arm valve train to a roller rocker system?

all suggestions appreciated. My AP14H is in need of a new feedback sensor, SLF12. Since the system is obsolete and the feedback sensors are unreliable does anyone know of a suitable replacement for the sensor or care to recommend a particular autopilot? Simrad, Garmin, Raymarine ? What say you?
