I thought the 39 didnt like speed over 100mph?

need to check your prop slip and go from their.. I dont think 6 blades will do much.. what rmp and speed@ wot?

Congrats! Was that the one listed on-and-off on eBay for a while? Nice boat!

Wrong, they run just fine 100+.

I didn't think they would run over 100 with stock 600 SCi's?
