    Dear Fellow Sailors, I need some wisdom in removing my inboard engine. The engine itself works well but the oil pan leaks and the transmission is shot.

    Yanmar YSB12 not starting

    I'm not a diesel engine expert at all and I'm having an issue with getting the engine started since the last time the boat was out last week. It was working fine until we were returning to the dock and, after reducing throttle, it died (fortunately we had enough momentum to coast the rest of the...

    Replacement Fuel Tank Recommendations?

    Upon removing the 12-gal aluminum diesel fuel tank in my 1979 Hunter 30 for cleaning, I found it was leaking from multiple pitted areas in the welds. I called around about getting all the slime cleaned out and re-welded, but it was considerably more costly than a new tank. There's no...

Does anyone know if the 75 gallon fiberglass water tank under the sole at the base of the companionway can be safely converted to diesel? It has already been contaminated with diesel by previous owner, and we...

    Yanmar 3GM30F engine RPMs fluctuate when engine warm

    Hi, I have a 1985 3GM30F installed in a Hunter 336. It's been perfect for 21 years. This year, the RPMs have started to fluctuate. When the engine's cold and for the first 20 minutes of operation, it behaves normally. After about 20 minutes at cruise speed around 2,500 RPMs, RPMs fluctuate down...

    Grounding Dockside AC powered pump for Diesel Fuel polishing

    Have 150 gallons of fuel in two tanks that I believe has the pox of diesel fuel critters. Age of fuel is unknown, likely more than 2 years. So filtering the critters is planned. Knowing this is a first time event for me I've been researching ideas. Have located a pump and filter system...

    What's the best way to clean diesel exhaust soot?

    i recently had an engine exhaust leak near the transom of my Catalina 30 and now most areas in the lower cavity of the boat, from the transom to the engine compartment, are covered in diesel soot. What is the best way to clean this stuff off of wood, fiberglass, and the engine? Thanks!
