HI All, I had a request for infomation on the Motor and Gearbox setup that I have fitted into a Wavemaster, a Sea Commander, and Fireboat, all shown in various posts of mine. The gear boxes are fitted with a 2.92:1 reduction gear, and were purchased from Hong Kong on Ebay, this is the information if I can publish it in this post. I mount the gearbox this way up to position the motor in the boats as low as possible.

I have a set of mouldings for one of these and was wondering what to do with it. What motor / prop / esc are you using ?. Have you any further photos. Would be very interested in any other details you can give .

There were several different versions using the same hull. Either way I think the conversion will be fine.
The prop is a standard item. I think I might have cut it down a bit but with the brass bush reused.
Receiver is a 2.4GHz Planet R6M (6gms MICRO 6CH) with a 1A Action ESC (with reverse). All housed in the forward cabin accessed through forward hatch (added by me).
Rudder control is achieved with a micro (cheap) servo tightly fitted into a styrene box below the stern seat. I attached a tube to the rear of this box to provide the axle for the idler gear. Nylon gears part of a standard set you see at trade fairs. Rudder an old KielKraft (1" wide and 1.5" deep blade). I've made the stern access in two parts the seat and a rear plate over the transom to ensure complete access to servo, rudder and gears.
I used a small old brushed electric motor from my 'come in handy box' on 6v. this drives a 25mm 3 bladed plastic prop via tubing universal joint.
A 4xAA pack of rechargeable cells is stored under the deck as close to CofG as possible and in a resealable bag. I can just remove it if required through a deck amidships. The main deck is planked and non-removable.
The switch and charge point is mounted by the helm and easily accessble.
All up weight is 295gms. Freeboard is fine even when a little choppy and she is quite stable. I was going to put a cover over the cockpit but have not found the need.
I do have some more photos and will try an upload them. Good luck, this was a very satisfying conversion and I still enjoy her as a quick an easy boat to prepare/handle/carry and operate.
Regards,
Jim Dewar
