I have a Boston Whaler RAGE 15. What can I do to help [the boat reach hydroplane] besides putting my wife on the bow?

Put somebody else on the bow?

You may want to have her looked over, they should not be that bad out of the hole with 2 people.

Just curious, but at full throttle, can you reach Max RPM range? (Not sure what your motor would be) If not, then you may have too large a pitch prop.

When I was proping my 13' Whaler w/40HP 4-stroke Yammie, my first prop had too much pitch. Only got about 4800 RPM, was really fast, but very slow to plane out. My 2nd prop has too little pitch. Maxed RPM 6000 at 2/3 throttle, really slow, but would jack-rabbit to plane. The 3rd selection was the perfect compromise.

Good luck.

check your engine height on the transom. if it is down too low, you will get lots of bow rise plus have tons more drag in the water. Both will inhibit getting on a plane.

Max and John:

BCT has a Rage with an inboard and an impeller, not an ouboard with a prop.

BCT: My 1993 Rage with the weaker (50hp Yamaha) pops right up on a plane with my lard--- (205 lbs) at the helm. The main complaint I have with my Rage is that it porpoises when empty, possibly because the nozzle is aimed a little too high. Your 115hp OMC should have no problem getting on a plane. Does the engine run properly?

I'm not sure if it runs properly (have nothing to compare it too). It is very cold natured, I always seem to have to choke it to start, and always hearing the overheat warning.
It seems if I let it idle a bit after I run WOT it does OK.
As far as the plaing off it just doesnt seem to want to plain very quikly.

Thanks for yalls help

A couple things. The jet pump on these is what circulates the water in the engine(no water pump). On my old Jet ski, I had a planing issue and an overheat one as well because my impeller was screwed up ALONG with my pump. There has to be VERY tight tolerances between the two or else you get MAJOR slip.

[Changed TOPIC; was a misspelling of hydroplane.]
