Yamaha 90hp fully rebuilt
I have a Yamaha 90hp two stroke for sale. It is a early 90's model which I have spent an absolute fortune on it and completely rebuilt it for use on my Humber attaque, however on reflection I think it is a little bit too big for my 5.3 so I am putting a Yamaha 70hp back on it.
It is not the usual worn out eBay special, I completely rebuilt it last year using only genuine Yamaha parts throughout. I worked as a Yamaha outboard engineer for 18 years so know these engines like the back of my hand and have all the factory special tools - it was not bodged together in a garden shed by a part time expert!
the powerhead had the following :
- block re bored to +0.50 oversize and ports accurately matched to correct production tolerances (standard porting)
- block checked for corrosion or splitting around liners (poorly maintained 3cyls can suffer from this)
- 3x new genuine 0.50 Yamaha pistons and rings.
- new genuine main crank bearings throughout
- new genuine small end bearings, big end bearings, new conrod bolts.
- all new genuine crank seals, head gasket and gasket kit.
The crank and con rods were thoroughly inspected and have no wear, pitting, blueing or damage to them.
It has also had a new latest spec genuine stainless steel gear shift shaft (notorious Yamaha 3cyl weak point), new stainless tilt stops, new trim ram seals, new impeller and various other gaskets. These parts alone cost well over £1000.
The engine is in very good cosmetic condition, no damage to skeg, propshaft runs true, gear case is not split, autolube and power trim work as they should. There are no broken bolts, stripped threads, corrosion, seized fastners or any repairs of any kind. Only bad point is the cowling decals have faded in the sun.
The engine was a good engine to start with however I wanted to know it was 100% perfect hence I stripped it and rebuilt it to as new condition. Since fitting it to my attaque, I have run it in and used it probably 30hrs however I think it is probably a bit big so am going to go back to a Yamaha 70hp as I don't need the 90hp power.
Complete with 703 control box, Quicksilver fuel filter setup, and control cables.
I am looking for £1900ovno which I think compared to similar 85/90 hp Yamahas in unknown condition at £1500 is good value for a 100% engine.
