EFNR1083DD9. Another 90 coming out of retirement.

Postby Henk » Sun Sep 24, 2017 4:19 pm

I tried to resist. Honestly....

Bought a tatty but running 90 today, needs a stripdown and plenty of tlc, but first impressions in the bin were of a good running gull, and a fairly smooth gearbox. The recoil is working, if a bit stiff. Not checked the alternator output yet, I'll hook it up to a battery first.
Bad bits are a repair of the cylinder block, and a build up of rust around the exhaust tube flange.
In two weeks when I have time, I'll strip the top end down, and drain and check the gearbox. The pump is pumping water aplenty, but whilst I'm at it, I might see if I can replace the impeller. John can expect another email soon...

Really cool!

Great motors and you have a generator as well?

The block will be your most serious issue I am afraid.

Your friend Ebay and good luck. Maybe others here have a good one for you.

Thanks. The seller told me that his friend had fixed a 'pinhole' in the cylinder, that it was stronger than original (yeah, right..) and when I mentioned that the head would have to come off ( pile on the negatives to drive down the price ;-) ), he insisted that that was not a good idea. The overall condition is quiet rusty and indicates neglect, but in the bin it started on the fourth pull, and runs well. The gear box selects forward and reverse, and back in neutral without problems.
Next week we're going to take the boat out, to try this one out, and give the fourty plus a run out (an excuse to go boating is a good excuse), after which I'll strip the 90.

FIngers crossed..

A few more pictures. Does anybody have, or know where I can find, any info on the alternator and the connector that iscattached to the wire. I wonder if it's original.

Treat the lower unit with care, quite a few of the internals are "no longer available", if would be a lovely gearbox if it wasn't so big!

Gear selector assembly seems to dissolve, & gear rod bushes/seals no longer available.

You should be able to find info on the alternator somewhere on here, as they've been discussed several times.
Make it idiot proof and someone will make a better idiot.

Thanks Charles, I am not going to take the gearbox apart, as it works fine, and when I checked the 'oil ' it was a good, creamy emulsion, rather than the crud that came out of my Fourty earlier this year.

So, today we managed to take the 90 out for a proper test run pushing our 16' cuddy around Swansea Bay. After an uneventful launch, and with my dearest beter half up to her knees in water holding on to the good ship, I commenced to start the 90. It took a fair few pulls, but into life the Seagull barked. A full flow of water out of the tell tale, the dear beter half climbed aboard, reverse was selected, and of we went. There is a certain satisfaction in getting underway with a new boat and/or engine....
Away from the slip, forward gear, and away.
The 90 pushed very well, an indicated 6 knots maximum, but as it's a free gps app, I'm not sure how accurate that is.
But, then the Gull started smoking, and stopped pumping water... aaahhhh. Engine stopped, and the trusty Fourty started up (second pull...), to take us back to the slip. It was immediately noticeable how much more effort the Fourty had to give, and that the tide and flow were much more noticeable than with the 90.
At home the Fourty went in the bin to flush, and I've started pulling apart the 90 for a clean up.
Pictures later.

A short clip of the Seagull disturbing the peace at the Mumbles...

Oh dear.
It's like getting underneath a Transit (don't ask me how I know this..)

Time for a replacement block methinks as that one looks like it's had its day.
Now you've got some experience with a 40, a 90 should be fairly straight forward. Rusty nuts and bolts are treated the same no matter what motor they're fitted to. (heat and soak with penetrating fluid before you get the spanners out, you've been there before)

Gearboxes (provided you're careful) are not that bad to strip down. Careful with the selector rod though.
It should be a nice dependable seagull once you've got it sorted out.

Surprisingly, all the bolts and nuts have so far yielded without recourse to either oil or heat. I'm going to look for a new block, but in the mean time I'll [s]bodge[/s] repair the one I have, as it runs ok, and I have the 40 as a backup.
I was quite impressed with it, it pushed the boat with ease, despite the 40 mounted and a small tyre ( fender/foot hold) still dragging over the side. I will have to raise the transom about 3 to 4 inches though, as it was sitting to deep in the water.
