Put the new steering damper on today, old unit weighed 3.44kg all in, new one is exactly 0.5kg. Pretty decent saving and on the maximum stiffness it feels on par with the old one.

A couple more wee things done, got the lower cowl and gearbox painted.
I sanded the skeg down some more along with a couple other tweaks.



Also designed a new cap for the end of the tiller, the trim switch always annoyed me. Probably saved around 20 grams too!

Nice work you are doing here! been following for a while as a guest.

What work is involved to convert a long shaft 70 to a short shaft? , cant find any info on the net

I can see yours was a modified long shaft, so its do-able ..

Thanks very much.

Mine has only had the mid section cut, the gearbox, transom bracket etc. is all genuine CES. The mid was already cut when I got it, it's a neat job, looks like you can just cut and weld the sections together with 5" removed. If you were starting with a normal long 70hp you would want to change the gearbox to a smaller 13 spline box, either the 1.86 from a 55 or the 1.71 from the racing 70c or 60d

okay, looks like I can get a original 70ces, it has a 1 piece head (thought they all were) trying to get more info on prop, tiller, pull start etc ..

Sounds like a good engine, the 1 piece head is quite a bit faster. None of the 70CES came with pull start, you can convert using parts from the 60 Yamaha enduro, need the bracket, pull start pieces for flywheel etc and the cowl.
You can use almost any tiller, the newer style like Iíve got you need to flip the gear inside the tiller to convert from push to pull. Thereís a kit you can buy now for £25 odd I think.
Only props that came standard on the ces are the 19G and 21G cleavers, both very sought after props nowadays

Been doing bits and pieces to the boat, tried some flexi paint on the fuel tank which seems to be working alright. Not sure how long it will last though


Got an update today on the new boat, looking good, very pleased with the black valves instead of grey


Engine is nearly ready too, I'm away march until june so doubt I'll get a chance to test it, will be exciting times when I get back
