Re: Yanmar 2QM15 Tranny Noise

Hi Brian,

I'm another spirit 28' owner up in the bay area. I've become pretty attached to this little boat over the last few years, but I don't currently have a tach.... do you happen to know how many teeth are on the flywheel? I believe it should say on the Yanmar tachometer gauge. "P-??" . I popped a new sender into the engine, but I think the PO was in the process of setting up an alternator based tach, so the gauge was swapped out on mine.

Thanks for the help,

PS: forum rules won't let me DM yet, so i'm hoping that replying to this old thread will work.
