Ok guys time to report back all well with compreesion spark ok and fuel plenty still no joy although when i lossen of spark plugs it fires up and starts so my conclusion is that the starter motor is weak would anyone aggre or any other suggestions why it,s doing this once it started i shut it down and tightened up plugs then nothing anyone give me the part number for new starer thank,s

If you have a shop near by that rebuilds car starters and alternators I'd take it to them. Would be cheaper than buying another one. Also shouldn't run it with the plugs loose. It's not safe and can damage the engine.

Mamy thank,s for reply i see you can buy a sterter repair kit think i,ll go down that road much cheaper so you would aggre that this could be my problem cheers

Spray a bit of WD40 on the shaft. If it spins freely after that then use a small bit of light oil like sewing machine oil. Probably just has old grease and dirt on it. Usually works and it is cheaper than rebuilding itif you don't have to.

Many thanks internals well worn and baseplate that holds brushes shot to bits new parts should arrive soon putting gearbox back on today I'm a little confused regarding gear shift height now are these measurements taken from the top of the gearshift housing or the Base I Can only seam to get the 20# from the top of gearshift housing but seams to be knocking it into gear on the way up to top linkage any ideas where I'm going wrong thanks

Long shaft, shift rod should be 20 29/32" to center of hole + - 1/32", the offset should be towards the rear. Not understanding why you are knocking it into gear.

No Title

Many thank.s bonz i can understand the 20# part but don't understand these other numbers 29/32 +1/32 when I try putting gearbox back on i think the offset top is pushing down on gearshift and knocking it into gear i will try again with offset facing the back of the boat thank.s for all your patience as this is my first bigger engine cheers hope these pics help. ...

Yes you need to measure from where you have the ruler in the 2nd picture.

The length from the face of the lower unit to the center of the hole is 20 and 29/32 inches plus or minus 1/32". So the longest you want to be is 20 and 15/16" and the shortest would be 20 and 7/8".

The shift rod is most likely hitting the rubber grommet as it's passing thru the lower shroud.

Yip spot on that's exactly what was happening many thank.s once again guys thank.s for all your help will rebuild tomorrow Scottish midges are out in force tonight

 

[bikerboyfife]

Ye ha guy's many thank.s for info new starter motor fitted fired up was a bit tricky to keep running not wanting to idle though will only start with a big 70ah battery is this normal once again guys thanks

 

[bikerboyfife]

Ok guy's next issue is she fires up and seems to be running a bit fast will only stay running when cold start lever at hand controls is half way up then when i push forward to move of it instantly stops running HELP

 

[bonz_d]

Shouldn't be able to shift it with the warm-up lever raised. Not idling I would guess you either still have a dirty carb, idle screw needs adjustment or weak spark on one cyl.
