Vee hull is the way to go-I run cats only when the water is relatively smooth,Even a slight chop can make a cat hull flip at higher speeds.

Usually the water pickup is mounted straight up and down.If you can blow through your cooling system it should be working-some larger diameter tubing might help increase water flow.Most of my boats...

At slow speed you may see little or no water but at higher speeds you should have a steady stream of water coming out.After a run, the motor should only be warm.If you can't keep your fingers on it...

No need for a marine receiver as long as it stays dry.I take my receivers apart and spray them with corrosion x in case they get wet.Lipo won't work with stock esc unless you use a voltage cutoff for...

You can almost buy a Shockwave brushless for that without radio on Fleabay.My buddy has one and it's fast with 3s lipo.

I have had similar problems after taking on water-I take the rx apart and spray with Corrosion X. This stuff is great and I have even brought dead rx back to life this way.

I would go parallel to lower the amp draw on the batteries.It must be a good sized boat to handle all that!

You definitely would be better off with the brushless setup for that size boat.I have a 24" shovel with a 540 motor and it gets on plane ok but I wouldn't say it's fast.

I would say they are grease fittings as there is no need for water lines to connect with the shaft tubes.These were common on Graupner boats with solid shafts.Probably meant to save you the trouble...

RE: Tempest airboat

I like to back the hole with thin plywood and fill it in with epoxy or fiberglass resin.I don't know if epoxy can be colored without affecting the strength.

RE: Boat electric question?

Thanks for the advice-I run a Kershaw 700 in my old ElectroVee hull with a 4mm flexshaft and it runs great.I thought the EVX supplied 14.4 V to each motor so I bought 2 Titan marine 14V motors for...

RE: Motor Can

Without drilling and tapping for a larger screw,you might be able to wrap a screw with Teflon tape and get a tight enough fit that it would hold.

RE: Newby driveshaft question

The shaft should be a tight enough fit in the stuffing tube so that all you need is some grease to keep water out.
