Best Power Option for 74 Sceptre 20 OB

[ssscotty]

Greetings, first I would like to thank the moderators, senior members, etc., for this site and the helpful advise I have received. I have been a fan of classic SeaCraft for some time and always dreamed of owning one. finally this year I was fortunate enough to buy a SeaCraft. now im a proud member of csc.

With that said, as I get used to her I have questions as I am always trying to improve safety, functionality, and performance. have a 2001 Johnson 150 ocean pro which is definitely enough power. my issues at this point is weight in the stern and fuel efficiency. I love its performance, but at slower speeds the stern sits too low for my liking and forget about if someone is back there. with just me and my dog it sits a lot better, even feel comfortable to leave the scuppers unplugged. I believe my motor weighs about 380 lbs and I have 2 batteries back there. I do plan on moving them to the front consoles eventually. was thinking about repowering with either a slightly smaller 2 stroke, or a more smaller 4 stroke. think im currently getting about 2 mpg but definitely not more. will I gain fuel efficiency with a 4 stroke? will it still be peppy enough ? if I drop to a smaller 2 stroke will I gain fuel efficiency without loosing much in performance do to the lighter weight? of course with the 4 stoke less smoky and quieter which is nice.

any thoughts will be appreciated....? thanks
