These motors weren't favoured by the racing fraternity, due to the 1.3l Yams, Soozooks & Twatsoos being faster.

Check the compression on each cylinder - if they're all ok, then you should be able to sell it on, 'cos it could be cheap power for someone on a tight budget. Like all Mercs, their appearance stands the test of time very well, so it should look very presentable for a 20+ yo motor, when advertised for sale.

there are a lot of bad ones around but that is due to age and hours on them and not a reflection of it being a bad engine.

There are also a lot spares as many were not serviced and not flushed out.

The only down side is as the amount they drink, but for cheap power and lots of it they are great value.

I think I will stick to my frugal 4 stroke but the 90 sounds the business! Fleabay should get it moved on at a fair price
