all,

about a month ago i posted that about 3 questions pertaining to a '75 evinrude 50hp that i was looking at on craigslist. in case you don't recall, i'll jog your memory:

1] the seller claimed it idles too high and that his mechanic told him it needed the carbs rebuilt. i asked here if that sounded like a reasonable possibility.

2] turns out he was flooded with offers as 50hp motors seem to be exceedingly scarce in the entire 3-state southwest region...so i impulsively bought it, sight unseen, based on several phone conversations with him. he seemed very much like a straight shooter, so i took a chance. the bonus was, he was only about a half hour drive from me. so the next thing i asked you all was about which way to lay it down in the back of my vehicle.

3] then, i realized that it _might_ have been an electric shift model, with solenoids and stuff that are NLA... so i posted here and found out it wasn't, [remember, i still hadn't even seen it yet at this point, except for pictures he emailed me]. turns out it was not electric shift, WHEW!

i paid $400 for it, which was a LOT less than i had seen any solid-state ignition-era, 50hp motor capable of running, offered for... still, one of you reminded me of the possibility that it might have bad compression and that i might have wasted my money. and yes, there was that chance. once again, the seller was so conscientious and honest sounding and the price was so good for such a rare item, that i took the chance. of course any good con-man will be good at sounding honest, right? :)

in any event, today, i finally got around to hooking it up to a battery, [it came with full controls AND two unopened carb kits, btw]. so i pulled the plugs and attached the compression tester. it spun right up like it was born to do it! and...

GOOD NEWS!

compression was crackling good:
157 on the top cylinder
163 on the bottom cylinder

i wish they were closer together, and it still doesn't mean the piston aren't scored. also, the exposed metal part of the coils is rusty. i'll throw my spark tester at it here soon. but that it cranked right up and threw out good numbers, to me is a great start.

now, i have to build a stand to run it on, because the boats i own already have motors on them.

there are many rust coils running strong.

making this an ongoing saga, since i bought this motor sight unseen, and there is understandable concern that it might have been a ripoff. well, in the first installment, i did a compression test, and it was crackling good at 155-160. paid $400 for this 1975 evinrude 50hp.

today, after who knows how long of sitting, i built a stand and put her on a battery. well, after jiggling some connections that sat too long, she cranked and fired and ran real nice! woohoo. :)

but only partially...my thrill got a dousing when i find that there's milkshake in the lower unit. looks like i'll have to pull it and order up a seal kit. :(

...and hope there's nothing wrong in the gearcase besides a seal job...
