New to me 6hp Evinrude project

[crosbyman]

The green  pics were  just an example of the level of carbon found in my  green 5.5hp Johnson  which is why I still wanted to pull the PH on the blue 6hp of my post

I’ll pull it anyway to inspect everything & maybe clean out some junk in case   it  is anything  like my 5.5 Johnson

I am ok with the  6HP base gasket   I have the necessary spare  with the correct profile.  I refurbed  a 6hp years ago  and  sold it to a friend but kept the extra  spare parts 🙂

next is dropping the GC  ( on blue) for inspection and pressure testing.  If OK i’ll  just refill.     Carb will be last   paint will wait for warm temps outside in May.

OK GC down… when I took out he GC -drive shaft …. found no ROLL pin below the upper brass cup…  I will try local hardware store

water pump impeller looked fine   bent blades (nornal & flexible) so the last guy who worked on it likely destroyed the roll pin, just took

it out or  just forgot to put it back  although removal was unnecessary

pump housing got a good brushing small holes cleaned out… new China  impeller 277181 going in…same size   as the old one  strangely for China  it has  bigger brass core . should be ok …

GC   refitted  with new  impeller……  such a pain  with the shift link clip reconnection…. till I woke up and took out the  bolt to let the lower shift  rod to slide in all the way  in     🙂

Those 6’s are known for idling down nice to be a great trolling motor.  Good price you got!

I got one about 12 years ago at an antique shop for only $35 because it was stuck, and had been badly brush painted to cover up a previous camo paint job, so it looks ugly.  The impeller had a couple broken vanes that were jamming everything up inside the pump housing, so that was an easy fix.   Runs good now.  I’ve used it for Boy Scouts to run while working on boating merit badge. Also used it for the first motor for my then 14  year old grandson to run on a Minmost hydroplane we built together – it planed it off!  Once he learned how to handle waves, I upped the HP for him  (and me!).

Did the carb this morning.. tough nut to take out on the port side but I used Leroy’s trick and  tilted the rewind spring 🙂

Carb  was essentially very clean.. I gave it a good shot  of carb cleaner . LOw speed needle was undamaged …. found the cork float near new 🙂 🙂  but I still gave it a  light coat of medium density  cryo glue sprayed with a mist of alcool/baking soda mix to instantly  turn  it rock hard.  The rest will be  general wiping and degreasing surfaces to be touched up  when I can paint outside.

a small  3″ travel spray bottle with 90 proof rubbing alcool and a 1/4    teaspoon of baking soda  makes a great accelerant.. dirt cheap compared to commercial stuff !  rings and cyl looked good when I popped the PH to inspect lower housing for carbon build up .

Did  the GC  check yesterday… no mono bird nest  found wrapped in/on the  prop shaft seal to chew it up .  GC  had  nice dark oil & no signs of water ingress. Washed down the innards bit with WD40  and will refill today.

I never did pull the cyl head  but a  good run with  a decarb  juice like  Merc PowerTune  should clean things up and hopefully bring up compression up  a few more psi.

Couple of chipped edges and  dings  need a JB rebuild before cosmetic work begins on outside surfaces. Some  ETEC blue  spray paint should be close enough…. (when it gets warm outside )     and  done !  🙂   It  will replace  the Merc 4hp & the 6hp will ride next to it’s  great great grandson 🙂

I think you have some detective work to do!  If the gearcase hadn’t been off before because the paint was still prestine on the bolt heads, how are the o-ring and pin missing?  Disassembly would have been required to get at them.

Red motor.  Is it the blue powerhead with primer showing through?

OR

Maybe the factory missed the impeller pin, the motor had some overheating which discolored the blue paint, and warped the cylinder head which reduced your compression.  If that wasn’t just primer showing through.

[crosbyman]

That is the underside of the  6hp PH  and  likely had  a poor paint job. I am not to worried about the overheat for now anyway…

PSI came up to 60+ and hopefully will come up a bit more (good enough as a trolling kicker)   cyl walls looked fine on the borescope and  side view of  rings.  manual rotation is smooth . thermostat was stuck open.

my feeling is that this will be a good runner  and aside from outside scratches  it seems to have  hadsome TLC ..and low use thanks to cracked coils.

thanks  for noticing.

By the looks of the  rotating “side post”  pushing the magneto I think this baby  never had the GC dropped because the top bolts were factory pristine

actually my comment  referred to the 2  bolts  heads holding the  clips on the top  of the rotating  side shaft controlling the   magneto rotation….. not the GC bolts.

I had  also referred to them initially   thinking  that removal  was   mandatory  to remove the PH to access the impeller as is the case fora 5.5hp  but as you know the shift  link clip  was enough to drop the GC .  Why no O-ring /roll pin   were  not  installed  above the carbon seal and below the brass cup  remains a   mystery ….may they were  removed with the PH off but the guy who did the work  left no traces …! .
