My 1985 43' motor yacht has 671TI's. Lately, the port engine has neen overheating above 1700RPM. I've checked the water pump (rebuilt last season), the strainer, coolant level. When I bought the boat 4 years ago, both heat exchangers were boiled out. What's left to check?

When I got my 53, it came with a very nice Garmin 2006C plotter on the flybridge but nothing at the lower helm. I didnt' really want to spent another $1500 or so since I usually run the boat from the flybridge except when docking or in rain. Since the lower helm is well protected, using my notebook...

I changed the filters, primary and secondary, on my 6v92's last evening, and I suspect that I may have gotten air into my fuel lines. I ran the primer pump until well after the bowl filled up, but when I started her up, she only ran for a couple seconds, and then shut down. When I opened up the...

OK, so I'm ready for the remedial lightbulb class. Could someone please tell me how to remove the protective shield and dome that covers the engine room 12v light bulbs? I can't seem to figure it out, and I don't want to apply too much force, seeing I'm not sure just what to force anyway. ...

Anyone have any experience with watermakers? Couldn't find anything in the archives. Sounds like a great device but I'm wondering if the manufacturers hype may somehow not quite represent the real world operation. I'd appreciate info re the actual operation/maintainance and recommendations for...

My port gear pressure has been spiking randomly the last couple times out. It starts out just over 200psi, and slowly works its way up to 400+. If I throttle back, it drops somewhat, but still is around 375. Taking it in and out of gear a couple times will sometimes bring it back to the 200 - 225...

Having read much discussion about generator replacement I think I am going to replace my 7.5 KW Diesel Onan with a new kohler Model 8EOZD. Anyone interested in referring me to where I might get the best deal on one please advise. Will Shelton 800-786-1272

There is no HIN number on the transom. There are numbers on the stringer in the engine room. They are about 4" tall and have a filter bracket over them. There are 2 numbers. I think that one is the hull number, 5201. Ther other number looks like NET 18... (the rest of the number is covered). ...
