[Teak Mouldings]

I would be inclined not to use ply as ply when it gets the odd nicks and scrapes it looks like S#%t, probably be best to use solid timber as its easier to remove bumps and bruises which all tables will eventually get.

[Yanmar Yse12 rebuilding]

I installed the smaller version of this motor the YSE8 in a yacht nearly 40 years ago. The engine was reliable enough but being a horizontal engine it was a bit of a thumper at low revs. Later versions (1980 onwards) of engine became the YSM8 and YSM12 the only difference being the switch to Bocsh fuel pumps. The original YSE8 and YSE12 were prown to excessive smoking (to the point of leaving soot on the transom and surrounding water when the throttle was opened, the later YSM series didn't suffer so badly from this.

This problem was purely because the original Yanmar ram type fuel pump was supplying fuel faster than the engine could burn it. The main disadvantage with these engines compared to modern ones is weight and the amount of space they take up. The gear lever needs quite a bit of weight to shift FNR so morse type cable controls won't work, it pretty much needs to be linkages
