Double post

I had that same boat and configuration, just be carefull of the out drive it's a pre- alpha drive (unless updated). I broke the one I had with a stock 260.

also the heads take a long reach spark plug, std ones for that are short, also need to run less total timing with those heads, keep max of 26-28 in a heavy boat...

I do have trim tabs already. I also have an Alpha one lower hooked up to the pre alpha upper. I was knockin on 60s door last summer with a chewed up aluminum prop. I bought a 21p Mirage Plus. Cant wait to try it out.

I have also read my timing all in now is about 30*. I was just going to back off my timing at idle by 2* so my total timing would be 28*.
