I had one went on to race bigger hydros if you were at the Nationals in Oregon in 1986 I was there.

Have you been able to measure the speed you were travelling?

It seems to be really moving.

Where can i get some plans to build one?

[MrJohnscott1]

What fun! I had a motor similar to that as a kid. It was red and cream i think... been LONG TIME

Beautiful boat and the perfect motor....Looks like a KG 7 racing you at the end of the vid?

Nice ride!! I had a bobcat 8 hydro, now a Heckle. Was it more fun to build or to ride??

@Darthmed0516

hey wonderful job how long did take you to build and i was wondering do you think it would be possable to use a jetski engine and if so how do you think it would handle

[Mark25H]

Thanks for commenting. There are plenty of flat bottom wood boat plans that would work great with a jet ski motor. But a hydroplane hull will not work becasue it rides a cushion of air breaking the vacuum for the water intake for the jetski drive

That is a beautiful hull,congratulations on the construction of it.I did see a Mark 20 and a Mark 25 by the looks of it but I did not see a Mark 20H.That would have been green and gold.Thanks for sharing with us.Ron G

[Mark25H]

The red motor is a mark 25 power head on the mark20H lower unit.
