I´m going to swap engine , from a 1988 175hp engine to a 1996 190hp engine. I wonder if the engine does not fit right when I have alpha one gen 1 and the new engine has been sitting together with a gen 2?. Are there any other differences that I need to take into account or that can make it...

1988 270 Sundancer with Twin 4.3l 175 hp alpha one. I'm about to change props. From 3 blade (according to photo 20x19, can not be correct?) to 4 blade. What prop size is recommended? Thinking about to replace with solas 4-blade 14.25x19.. I hope to mainly reduce fuel consumption.

I'll start a new thread.

Hi. I have a 1989 270 Sundancer with Twin 4.3l 175 hp alpha one. I'm about to change props. From 3 blade 20x19 to 4 blade. What prop size is recommended? Thinking about solas 14.25x19..

On my alphas the prop rotation is the same on both of them. Is this standard? If it is, why? I thought Lh Rh was standard.
