Yanmar 2qm15 smoking in gear
I recently purchases a Spirit 28 (79) with a yanmar 2qm15. the boat had been on the hard for a couple of years.
The engine has been relative well maintained, and I have changed the oil, drained the fuel, refilled the tank, changed the fuel filers, and oil filter.
the engine starts up in a second, every time. In neutral she rev's well and sounds great.
As soon as you put the engine in gear she struggles, and smokes up quite a bit. After a few few minutes in gear she will pick up power and cruise at 6 knots. But the engine still sounds like she is struggling.
When you throttle back she waivers and nearly cuts out, and then if you slip into neutral she picks back up and revs up. .....
..... I have no idea what to make of this situation. Can anyone lend some advice?
