View Full Version : Fuel pump cactus on old Evinrude

I have an old 25HP evinrude 2 stroke that came with my boat, I thought it was not good for anything but a spare anchor, but mate has had a look at it and it runs well, apart from it stopping after about 30 seconds.

The fuel pump on it looks like it has gone to the great fishing ground in the sky. (the pump case is cracked, and all the diaphrams are stuffed) It runs fine on a gravity feed, but I reckon it would be a bit hard to carry a 20 litre fuel drum 3 foot above the motor all day!.

I have a few questions hopefully someone can help me with

1. How can you tell what year these oldies are?

2. In case I cant work out the year, how generic are these fuel pumps (IE if I am really lucky they used the same one for 20 years!)

3. How many arms is it likely to cost me for another!

4. Can you use an independant fuel pump? (Got an old electric unit floating about somewhere)

Well have gone over it with as fine tooth comb. No ID plate.

However there is a little spot a bit cleaner, with a couple of rivet holes, so I suspect the ID plate has gone walkies.

Dang the motor might be hot, (although why someone would steal such an old motor is beyond me).

Will ring the drunk punchers today to ask their advice.

feral.

those 25 hp fuel pumps are all the same... very little difference from a mid 80s pump to one of today :o

Also a 20 , 25 or 30 hp pump will fit as well.. any half decent wrecker will have a bucket load to choose from

cheers

Thanks Fella's

Got one off an old johnson mate had in back of his shed, motor was only an 8, but pump looks identical, will give it a go. If it does not go, off to the wreckers.

Well pump worked fine, took a half hour or so of cursing and fiddling, and burning old fuel and gunk, but then she ran well, then worked out choke throttle settings etc so she fires first pull, and runs sweet as!

Only problem was then when put her into gear, the prop did not spin!

Was running late so left it at that, got halfway home and remembered that props have shear pins! Now I'll spend the night wondering if it is only the shear pin, or gearbox problems!
