Back in the saddle..... Again.... Again

[Blankton]

I made a post about my new (to me) sib outboard last week, but it got deleted, so I thought I'd try again.

I picked this up from gumtree, had to pay top money (£1350), but it seems very tidy and in genuine condition, i.e. It's not just been tarted up with a rattle can.








A bit of dirt and grime, but no evidence of corrosion or of any overspray from a tart up job.



I ordered a service kit and today I did the power head end of things - plugs and fuel filter. Not much else to do on a lovely smoker 😂. While I was there I did a compression test. 80psi on both cylinders, which although it seems low, is what I also had on my old 9.9 yam (that I should never have sold).

(that's a bit of old grease residue in the bottom of the housing, not corrosion)

I have never got high compression test readings from my yamaha outboard, I have read somewhere that the valves on certain models lower the readings, it always ran fine.

That Yamaha looks really clean. Don't worry about the compressions as long as they are even and not some daft low figure. Gauges can vary a lot as can ways of pulling over to do the test.
