Smokey Volvo Penta's
I have twin 200hp Volvo Penta's (TAMD41) and on start up they smoke out the marina. After they warm up they are just a little better but still extremely bad. When I am cruising along they are fine, but when I'm at the marina their bad.
I went for a cruise for a couple of hours yesterday and after I returned to my berth I noticed they were smoking badly again, so naturally I shut them down so as not to smoke everyone else out. Normally after a cruise their ok but yesterday, they let me down sadly.
Can anyone tell me how to address this without changing the injector tips. I am hoping there is a fuel additive that may work but I would like to hear what other experienced boaties do to solve this issue as I am sure I am not the only one with this problem.
Many thanks in advance.
