Default 80 +

Dyno,

There is a 31 Sonic that runs in South Haven.
80 + I think he has around 600 HP.
I'm sure Mark / Kaama knows him.

The fellow with the 80+ sonic runs with
Larry Hollenbeck with the 41 Sonic / 104Mph.

I think Larry moved into an Ocean Express.
Anyways talk to Kaama and see what he has to
say.

Dyno,

The fellow that built his engines is
somewhere between St.Joe and Grand Haven.
I would know his name if I heard it, and it's
not Bruce at Wolfie's compition engines.

This fellow does it more as a hobby, but
is supposively real good.

Running Hot used to run with these guys
to with an active thunder. I see it's
for sale in the back of Power boat.

There is a '98 in our area with Merc 525 SC's and I believe it runs over 80 mph.

Yup, I've driven it. 89 on speedo, so 80-83 real mph. That was with B1 props, would be a little faster with Mirage Plus's. My boat picks up 2 mph with the mirages.

Thriller is Bruce Chapman's boat. It's mostly black with yellow stripe and silver "Thriller" letters. "Doctor" Dave Lorenz did the engine work. I'm not really sure how fast Thriller is, but he's had it for a long time, back from the Running Hot days. He doesn't run it that fast anymore since they recently had a baby that's with them, so he takes it easier till she gets a little older.

Doc Dave could tell you more, but he might fluff the top end speed. He always tells you low, then spanks you
