Reply To: 1956 Mark 30H and Keller deadman throttle

[Douglas Follett]

Terry,

The purpose of the rope is to keep the motor from tilting up and down during a flip which could cause damage to the motor and transom. Run the rope across the tower above the exhaust outlet.

Retarding the throttle 1/2 may or may not work.  You will most likely need full power to get on plane.  Once on plane you can back off.

A hydroplane works buy trapping air between the sponsons. Once on plane the the only parts in the water are the back of the sponsons and

the back by the motor. The rest will be riding on air.  Depending on motor height the prop will be on or near the surface.  My D hydro runs at 0 which is max height per APBA rules.

That is the prop shaft is even with the bottom of the boat. best to start low and work your way up.  The best thing to do is go to the APBA or NBRA website and see if there is a stock/mod/pro race near you.

Get a Pit pass (free just sign the waiver) and talk to the drivers and look at their set ups.  Racers are a friendly bunch.

Be careful, have fun.  Let us know how it works out.

Don’t know why my posts are double spaced. When I grew up the only computer was on Star Trek.

Sincerely,

Doug
