Guy had a second boat that he was burning as it had a leak , it was there that the original starter got stolen  from the boat as it was in dry dock to have the engine removed for storage as he owned the engine 5 years ( the boat ) and ran perfect the engine got dragged along the beach buy rope to be taken away to storage and in doing so sand had got in to the the air in take , and it been sat there 5 months till a picked it up from the garage , on closer inspection ( heads off to find it had sand in bore ) no starter to cross reference from ie direction off travel ....needed

Money received blindly .....am not blind ?

I dont think you should have a timing issue at all if you have not upset the timing in any way. The simplest way to determine the direction of the engine is to remove the rocker covers and rotate the engine and watch the valves opening and closing. It is easy to establish which is exhaust and which is air intake and armed with your basic knowledge of how a 4 stroke engine works you can tell what direction it is.
At least you can now say there is no sand inside the top end and hopefully none in the sump.

Hi Zvh

Sorry for the lang and slang! Blindly, means you get the money without knowing what task was comming with it (or not!).

Indeed you will have some task ahead.

My best wishes to you.

Can you guys tell me if the 35 on the plate stands for the build number , am still trying to work out witch direction the staring motor needs to turn , as engine turns over and blows smoke out the air in take witch am thinking the starting motors turning engine the wrong way , the teeth on the fly wheel are curled down  from age and use

But after fitting starter and checking directions its turning engine up over

Looks like yours is a post-1970 engine; so the serial number is a bit different.

35 = no. years after 1950 + 50 (i.e. 1985)
00091 = the engine number (so quite early in the year)
STW2 = the engine type
C = rotation - i.e. clockwise
01 = build number.

The "Unit" number is actually more like the pre-1970 serial no; which would suggest:
Unit no. 4792
Type STW2
MG = Marine Propulsion
85 = the year.

However, I'd go with the top number for your engine details.

Cheers!
Ade.

Hi Gentles

The second number seems to indicate MG - marine generator.

So it could had been taken out of his alternator.

My 2 cents.

Av manage to find a on line manual but theres very like in it about valve timing on the stroke , although there is some Mark's stamped on the back off the fly wheel that may be time related

There f/p and them 10 degrees later there wot looks like tdc mark and there another at 180 degrees from that but a carnt see the line up peg that there line up with or will this just be a case off stopping it at say the 3 o clock position
