Re: 1985 Bayliner 2450 Ciera Sunbridge Restoration underway!
Ok, i've sent the original prop off for a rehub and rebuild. The solas prop IS the correct one, its just designed differently (not as good) as the volvo.
Should have the rebuilt prop back next week.
sorry for the late reply , i have a 14.5x17 p michigan wheel on currently,,, and am running the mercruiser 5.7, alpha one (1.5 upper gears).. my original prop was the same all around before i hit the submarine!!!

. i havent hit wot yet, best i've done is 3600 rpm.. it just isnt capeable! however it does run nice at 2900 rpm at around 22mph gps and with the tabs its not too bad to get on plane.
i too am prop shopping and had my eye on a solas but i am looking for is the 15x15p size here on iboats.
that should give me 400 rpm which will give me closer to the recomended 4400-4800,,, ok not really but i am scarred of getting a 15x13p which the negative 800 wot rpm calls for. 2inch drop in pitch=3-400rpm. once i can get the admiral aboard to make the purchase i'll post my results(moneys tight right now)
so where do you stand with the current prop at wot?
i think the diameter also has to do with the pitch needed but not 100% i cant find anywhere that if you drop the diameter, what you need to do to the pitch to get the same result on the rpms at wot,,,,,, yep it is confusing
but i hope it helps
