the thread idea came to me a while back I just never did it till we started clogging up andy's LOL, but I kinda feel like we're the redheaded step child of skater LOL and don't really fit in at SF either.

A local guy put new 250sho's on an older 25 eliminator he stripped and re-rigged, guess I should look him up and see how it's running. I did notice the Yamaha stuff on the website when I went to check out his seal and vent kits. On that note...why doesn't the expansion tank have a vent???? when I pulled both my lowers I felt/heard a touch of pressure release when I disconnected the line form the shift seal quick coupling!

Maybe we need our own web site? "Scream and Rebuild"

That Merc V8 looks very heavy.

Why arent we hearing more about that "Seven" outfit with the caddy motor, and why didnt they call that company eight"?

I will gladly give up .25 mph to have hydraulic steering over rope and pulley. WTF?

Did Mike actually do that? I knew he was talking about it but thought it was cost phobitive. I know its on a 'toon but I love dad's SHO. Very impressive engine.

I would never join a club that would have me as a member.

scream applies to me but not rebuild YET lol. Hope that's many more hours in the future for me.

seven marine is a heavy beast that along with the price tag is what's keeping them from being used IMO. they did rig a 39 Nor-tech CC with trips 89.7 http://www.seven-marine.com/news/fir...en-marine-557s

just to compare

557-------Dry Weigh 1094 lbs. 557hp prop shaft power @ 5400rpm

300xs---- --- 505 lbs.-534lbs. 300 drive shaft hp @ 6100

I originally wanted to use Seven Marine OBs on a 32 flatdeck but the weight cost and lack of local maintenance support made it a no go. Later when I decided to use the LSAs on 338 build it was all good until they went to the dyno. GM also stated that prolonged use above 5400 RPM would lead to catastrophic valve train failure. So that being said I wonder about longevity if the LSA on an outboard application.

BTW the cost of a crate marinized LSA and ASD 7s was less than a Seven Marine OB and lighter!

thought I remember seeing pics of it??? maybe not LOL.

I have been on a few CC with 7 marine engines and not all that impressed. Like Skate we have entertained the idea of a 32' Cat with twin 7's but the cost is ridiculous. Also not sure how all the weight hanging on the back will hold up. CG would really tough.
I agree with Craig, outboard skaters are the step child here on OSO. On scream and fly we do not fit in either. So now we have a home!!

This is going to be a sweet thread, outboard skaters may not lay down huge top speed numbers but they are great boats and they really started it all for catamarans.

What i cant believe is how so many power sports have products that continue to improve in efficiency and power where outboards seems to have been moving much more slowly. I mean the 300xs is a great motor but it has been unchanged since 07.

Someone needs to build a widened 30 like the 338's but with triple 300xs!!
