Flush or muffs for 1968 Evinrude 100 hp

[autoarcheologist]

I'm just about ready to start our 1968 Evinrude that has been dormant for years. A mechanic put a new water pump in it, and I just replaced all the fuel lines and a few suspect wires.

I'd like to hook it up to water rather than dragging it all the way to a boat launch for the first test. But the water intake is just behind the prop, and from what I have read the original flush kits are long out of production.

Has anybody removed the water intake housing and hooked a hose directly to the tube inside? That's my plan for this morning, but wondering if I'm barking up the wrong tree. A large garbage can full of water is my second option, but I'd really like to figure out how to run it on just a hose for future maintenance as well.

Thanks!
Ian

That may be one way of doing it, but you probably will curse when the inlet water tube falls out of the upper grommet. If you want, you could fabricate a hose adapter to fit in place of the oval plate on the side of the extension housing, just above the lower unit. You may have to somehow block some of the backflow out the main intake.

thanks for the tip! I split a garden hose about 4" down the end and wrapped it around the intake with 2 hose clamps, and it seems to be flowing enough to get water back out. I think that will work well enough for me to start it and see if it runs before heading out for a real test.

Alright, some progress. I got the homemade flush kit set up, then went to start it. Pumped the new bulb (the previous lines didn't have any bulbs, I'm not sure how they primed the system!) until firm, then went to try to fire it up. She fired and ran roughly for about 5 seconds, then died. I can get a pop or two when I try to restart it, but that's about it.

I pulled the plugs and cleaned them and they looked good. Turned it over a few times to blow out any extra fuel, then tried again. Again a few pops, but not much.

The PO says his mechanic had it running then drained the fuel, so theoretically it should run. Tomorrow when it's cooler in the morning I will test the spark. If it's got good spark I'm hoping I just flooded it.

I'm open to suggestions,, but I'm basically going through the "won't start" FAQ here: http://forums.iboats.com/forum/engi...ions-faq/162217-outboard-won-t-start?t=158071
