I installed the orange caps per Franks’ recommendation today, finished putting
the outboard together, and test ran it in the barrel. It started on the third pull.
It ran fair, but it didn’t sound like it developed full speed.
Noticed the reed block gasket and the transfer port cover were leaky slightly,
and one fitting on the gas line would not seal up.
Back to the bench, tightened up the bolts on the reed block and transfer port cover
and fixed the leaky gas line. Also remembered that I put a prop on it from a 5hp
Elgin, as the 3.5hp prop that was on it had a chunk out of it were the shear pin goes.
The props seem to be the same diameter, but perhaps different pitch?
This may be why it seems to bog out slightly at full speed.
The original prop had number 21265
the 5hp prop is number 22265
A 2.5 hp prop has number 19265
Out of curiousity, does anyone have a listing that tells the specs on these props?
I barrel tested it again and it seem to run a little better on low end, but when slowed
down to "slow" it would "cough" after a bit and want to die. Low speed adjustment
didn’t cure it, but when choked about 3/4 it did. Noticed that the transfer port
cover gasket is still bubbling / leaking a little.
It does not need choked to run fast.
Would a slight leak on the transfer port cover gasket be causing my issue?
Will try fixing that tomorrow.
Anyway, I think the orange caps are doing their job. Thanks Frank!
I removed the original guts from the Wico condensers and filled them
with red RTV that I had handy. The orange caps just fit between
the coil and points.
Wednesday Update- made a new gasket for the transfer port cover and
installed a prop from a 2.5 hp Elgin. Had all three props on the bench
together, and can see that are are all slightly different in pitch.
Test ran it in the tank. Winds up nice now with the different prop…
hopefully not too nice! Idles nice now, but still coughs once in a
while while transitioning from slow towards fast, but runs great when
at a steady speed. Anxious to get it on the lake….. looks like a great
trolling motor for my little AlumaCraft.
Video of it running for the first time in many years no doubt.
