Call Dorr's Marine in Windham Maine, ask for Tim 207 892 5145 -Tell him Kurt sent you.

Thank's Biggus, Tim had one 3" at a good price. Now I just need to find one more 3". Hopefully also at a good price. This go fast boat stuff is really hard on the wallet! LOL

I've been wanting to ad Chillers for a long time. I finally found a good used pair from an OSO member at a decent price so I bought them. Then I need water pick ups, strainers, braided lines, hose fittings, pressure valves, transom dumps, smaller pullies to get the lost boost back and oh yah, longer belts!!!!! Does it ever end? Probably not! Always want more HP!!! Thank God I have an understanding wife!

I've got one on the way but still need 1 more at a good price. 3 Inch 16 Rib.

That's why I sold my 250's and went to 420's. I wanted more power. Went from 250's single carb non intercooled, to 420's dual carb non intercooled. 7psi with the 250 blowers=82-83 on a cool day. 6psi with the 420 blowers =87-88 on a warm day. On a cool day, should run 90ish.

Still need one 3" 16 Rib pully. Anybody?
