Any experts on this subject ?
I have rebuilt my AQ151B 1 yr ago and now am looking at replacement of a 3rd cyl head removal to resurface the head & replace the head gasket again. Very frustrating as I'm using the best machine shops in my area who have marine expertise.
The engine runs...
Can I install a DOHC head from a AQ171 to my AQ151B eng ( if I can find one ) ?
Reason; looking for more performance on my 18' on a VP290D drive with a 2.15 ratio.
If this is possible, how much more perf might I expect ? dearborndeuce in BC thks
