Scandalous, an Ericson 27, now sports a 12x12 from Michigan propellars.
It is bronze with a 3/4 inch shaft, keyway, with left hand rotation. You
were right, a 14 inch blade would not replace the 10x10 two blade. A
Dual Pro Four Bank Pro SE is in place to charge the four wet batteries.
The Mars, brushed motor from Electric Yacht will be up in running
hopefully this coming week. Many thanks to Scott McMillan for quickly
replacing the one inch coupler to my 3/4 inch shaft because of my
assumption that I had a one inch shaft. I did replace the 200 amp fuse
with a 200 amp marine Bussman circuit breaker from Lessco Electronics.
Lessons learned, were not many. The prop shaft size and prop change over
should be carefully reviewed for adaptation to the electric motor
beforehand. The location of the four 12v batteries is paramount. The
removal of the old motor, fuel tank, wires, hoses, and miscellaneous
switches is the biggest task.
The installation of the throttle quadrant, key switch, circuit breaker,
and motor are a big jolt to a job well-done, and easily makes up for the
prop foul-up. Now to sell the 14x12 Volvo Penta p/n 850659 aluminum
prop.

Eric,
Are you sure you can fit a 14x12 prop on your E27? I ended up with a
12x10 three blade fixed and it works pretty well - 4knts @20amps. I would
like to try a 12x11 just for grins.
Is the Electric Yacht motor a brushless motor? When I was looking they
were brushed motors. The SoildNav Explorer, the one I installed in my
Ericson 27 is brushless.
Also if you are adding new batteries to older ones I would get a charger
that charges each battery individually. Like the Dual Pro Four Bank Pro
SE. I added a new battery to a bank after one went bad and the Kipoint 48
volt charger (which charges the whole bank as one) had problems. The Four
Bank Pro is keeping the mixed bank balanced so far.
I have two separate banks; 4 group 27 AGM's and 4 group 31 AGM's. The
Kipoint charger is on the bank that has all the same vintage batteries
and it's working fine on them.
