I am about to start on Tyne Tugs Alfred kit and I have found a hectaperm motor in the leftovers box from years ago will it be OK with this model I think the prop will be nearly 4". so something with a reduction gear would work best anybody out there venture an opinion ? Also what would be best for a speed control last time round I used Bob's boards (remember them) I assume things have moved on since then

I have a 12v Hectaperm in a Model Slipways Envoy class and it performs exceptionally well and I would hazard a guess at the prop being in the region of three inches.
I have had it on the water for well over an hour and a half and it hasn't shown signs of slowing down and that's connected to a 12v 7ah battery, which drives a JJC Old Smokey as well, although that takes next to nothing.
The only downside is that they can be a bit noisy so a bit of sound in sulation may be usefull as well as a flexible means of mounting such as a rubber or silicone base etc.
Apart from that I think it's a great motor and I'd be more than happy to use it again if I had the chance.

I have just bought a Lady Jan off of a fellow club member (just to get me back on the water) and it is fitted with a MMB 900 running on 6 volts driving a 3 1/2" 4 blade prop and I have sailed it pretty much all day on a 7ah battery so the motor must be pulling less than 2 amps on load (note to self..... Must invest in a decent multimeter) and it is quiet as well!!!

I would use an electronise speed controller every time, they are faultless, to save a bob or two you can buy them in kit form as well, they have never let me down, I have used allsorts of other ones but for tug work they are the best. I drive a bosch car fan motor on a 15amp one at 12 volts, my smaller tug has a 900 size motor with a 15 amp controller as well, you get no high pitchwhining or strange noises with them at all.

Hi, your hectoperm will be ok as long as you use the geared end, use silicone grease on the gears to keep the noise down & also you may not need a sound generator. It should run all day as the amp draw is negligible.
