Hi, Guys i currently bought 1991 Wellcraft Scarab 21" w/7.2L mericruiser and Bravo 1 stern drive...It has a 19p 3blade prop the guy i bought from told me he was recomended that prop due to altitude he was @7,000 feet... what type of prop should i get for this baby 3 or 4 blade what pitch and does anybody know how many splines this stern has?

when my motor was stock i was running a 23p mirage at sea level. Where are you?

Im at about 1,500feet above sea level, Thanks

I would recommend a Mirage Plus for your application.

Thank You...Julie im visiting your web-site

You have 15 splines on your prop shaft.

A 4 or 3 blade propeller could be used depending on your goals. Whether you are looking for top speed or water sports applications will make the determination.

Thanks,Brett im looking for a combo of both can you recommend one from your site?
