Got a new stuffing box as recommended. Hopefully this is a better choice? I will need to alter the bulkhead to accommodate the motor. Any other suggestions?

Hi Grandpa,
If you go back through the build logs to 2009 you will find my build log for the Kingfisher. I first made one when I was a school boy many years ago and later came across the plans at my parents house and decided I would try and scratch build from the plans but with a few minor mods (dump the hard chine in favour of laminate strip). Its a great little boat and is very stable in high speed turns. On mine I made the bench seat a drop in accessory and opened up the bulkhead to aford extra space for the motor connections. I'm now running a Speed 600 on eight cells and its got a nice turn of speed.

Hi Robert,
I saw that post when researching this boat, it helped me decide how to continue building the kit. If I do not want to use a water-jacket style motor, is there a motor you would recommend.

I have several battery packs;

One pack is a 4200 - 7.2 v NIMH
The other are two packs both being 2400 - 7.2 NIMH these are with connectors to allow longer run time.

Thanks,
Ron

P.S. I am relatively a new builder.

I made a copy of all the parts on a piece of 1/4" plywood.

Grandpa,
I started with a direct drive Speed 500 on 6 cells (7.2V) and it didn't have the performance I was looking for. I later changed to the Speed 600 and 8 cells (9.6V) and it made a huge difference. I'm not convinced how effective the cooling coil is as the flow from the outlet is not as much as I anticipated however this could be a function of the poor design of inlet that I'm using. Bottom line is I don't think the cooling coil is necessary. I make up my own battery packs and for this one I use two x four cells, one on each side of the centerline.
As I previously stated I was a school boy when I built my original and the hard chines nearly made me throw in the towel. As an impatient youth it appeared to take for ever to plane them to match the bulkheads hence my switch over to laminations of 1/4 x 1/8 on my remake.
Have fun and keep up with the posts.
Robert

Planning to use my belt sander for chines to match the bulkheads as shown in the plan.

I do other woodworking such as this toy barn, which I just finished for my grandson's birthday next week.
