Identify a Yanmar

Which model is this?

Most Yanmar engine model designations are on an engine data plate, on the front or the top of the engine. Some older engines have the data plate on the adapter plate between the engine and the gearbox .

A 1978 yanmar YSE8?? With some rust and dirt!!!Cheers.

GordMay · 26-10-2009, 09:18

My eyesight isn’t very good, but it doesn’t look like a YSE8, to me. This wouldn't be the first time I was wrong (if I am), though.

Or maybe is the YSE 12?? no big exterior diference betwen the 8 and the 12! what you think??

The boat is a 1978 Watkins 27.
I've not yet seen the boat, nor does the previous owner know its history.
The oil fill and belt arrangement should be good indicators, but I've not been able to match it up with pictures from a Seloc manual nor pics on the web.

edit: The dip stick looks to be directly below the oil fill.

But hey!! the front cover still have some grey paint, all the rest is rusted like hell, im 80% sure is the YSE family yanmar engines. I suspect the coupling and stufing box are rusted too.

I think it's a YSM8R or the YSM12R. The number plate is usually at the back of the engine affixed to the bell housing of the trans. It sure looks like my YSM8R though.......m

Nine Luft's original (& post #8) photo shows the water pump & alternator both to port side of crank, whereas the Yanmar photo indicates water pump to starboard.

Here is a pic of my YSM8R. All fresh and rebuilt. Now all I have to do is get the boat back in the water to see if I did it right......m http://www.cruisersforum.com/gallery...?i=6181&c=517]

cantxsailor · 26-10-2009, 12:44

I guess I did something sort of right to get the picture this far. If you need a better look go to the galleries................m

Looks like the same motor to me.

Regarding your rebuild:
Where did you get the parts, and was it a kit?
What if any major problems did you encounter?
Any special tools you needed?
How did you get the sucker outta the boat...

cantxsailor · 05-11-2009, 12:30

No major problems with anything as they are pretty simple engines. Parts are resonable as far as cost goes and are available if you can get someone who knows how to look to see what part numbers have changed and there are a few. I used the boom and a small chain fall to hoist the motor out. I have easy access to my engine thankfully. The only special tool was one to pull the cylinder sleeve out of the block made from some ready rod and some bar stock. Easy job but very dirty. Diesel engine oil is as bad as or worse than 5200 for getting on everything......m
