There is supposed to be some kind of spring in the turbo that gets stuck from lack of use. The stuck spring doesn't allow the turbo to spool up correctly. This is from recollection of stories I have heard. I never had to get mine fixed. I would try a few other things first to see if the problem is caused by something else that has simple remedies. Is your air filter clean. or is the engine laboring due to overweight or fouled bottom?

Is it smoking when it first starts up? hot or cold engine? running hard or just idle? white or black or blue smoke? lots of different kinds of smoke will tell you lots of different things.

Are you using oil? Also check your fuel filter and see if you have collected some water.

uses some oil filters changed out today they looked good engine is a 1989 the hour meter reads 1300 hrs. had 1125 when i brought the boat owner said they were original hrs. ?

is it just smoking at idle when cold? how about when hot or when running at cruise and WOT? I have a pair of 40b's and they smoke a bit when cold, one comes out of it but the other doesnt, i pretty sure the timing is retarded a little bit on that one. pretty sure volvos just smoke a little bit too.

I own one also, in fact same vintage. The motor smokes and about the only thing you can do is a cetan additives to help. In addition to that i also installed a Salisbury transom muffler which redirects the exhaust down, under water. It's a very good motor.

start up always does that just when running slow i got to look into that Salisbury muffler where can i get one because that is the only thing wrong with engine i do add additives to the fuel system

I would try using it more. The engine isn't even broken in yet and the you add the lack of use on to it.
