[NorwegianBoater]

Hi!

Was just wondering if anyone could tell me how many splines there is on the prop shaft on a Merc 90hp, 3syl, 2stroke 2006 model?

Thanks a lot

I'm not sure but i think you'll find a prop made for a v6 will not fit. Is the gear case 4"

My suzuki has 13 splines with a 4" gear case and has been a difficult job to find a prop bigger than 21" to fit it as bigger props are designed for v6 omc or merc even with a flo torq hub adaptor.

Thanks alot 1up that is what I thought to! Im really trying to find out if a OMC V4 Raker 1 will fit it and after what has come to my knowlegde now I think it will fit, just have to get the original OMC hardware to fit it (nuts etc)!

Cheers

Ive just bought a 22" (13 spline)raker from ebay moters, but yet to try it as have not been near my boat since it arrived so I hope it fits. Like you say i probably need the omc thrust washers I expect.

I tried my raker 22 by 13.5 this weekend, goes quite well, I gained 2mph and peeked at 58mph on my gps and dropped revs by 200, which i wanted as a was on the rev limiter with my 21" the prop fitted straight on using my suzuki washers, as suzuki use the same bush as omc. the boat did seem to get more lift and the prop did have a turning affect on the boat making it dip to the right slighly on landing after hitting a wave. the pullout or holeshot was abit slower so made skiing quite a stuggle but once i was up we were away

Sounds good 1up, hope to try it myself in a week or so
