I have a very good used Mercury 90 ELPTO on the back of my rib, I'm considering upgrading to a 4 stroke or ETEC.
The Merc is 1998, great condition, just had full service inc carb clean, plugs, oil, impeller and new engine mounts and gaskets all round. Runs very nicely and starts 1st time every time hot or cold.
Would consider offers on that if you're interested. Its located in Poole, Dorset. Certainly not spares / repairs, but you could fit this one and keep your old one for spares..?
