Jaemsie,
If that isn't what you need I'll see what my Clymer says when I get home. Could the mark have been put there randomly to make it easier to see with a timing strobe?


AHH,
The remotes Loom? Do you need one ?

Hi thanks for the info, still looking for something specific for my engine as there is some variation between the different 55 b's but much appeciated anyway

Not sure of the exact name of the item your writing about. The 7 pin plug or 10 pin for electric tilt (as part of the wire harness assy) is what i'd call it. By the way as 9d280 said the the M in 55BM does stand for Manual as in manual steering and starting i reckon your outboard has been converted at some point !!!

My clymer was for the Mariners, and from memory stops at '79. Having said that I also have the Mariner Clymer to suit my "new" Merc which conveniently carries on where the other one left off, although I'm not sure I remember seeing any of the 2 Cly stuff in it. Will check when I get home.

Yeah, I did think that cover looked a bit oldschool livery for a post '79 motor...... It's just occurred to me what that white sticker on the tray is - probably the one that told you where Neutral / Forward / reverse was before it was converted. Any grommet filled holes below it?

You got PM ref. the wiring.

Jamsey

2 settings according to clymer for the 48/50/60. WOT advance - 22 BTDC, idle 2 BTDC for the "Dual carb", WOT advance - 26 BTDC, idle 4 ATDC for the single.

So, usual Clymer one manual fits all.......

Thanks again. The 4 - 6 atdc (idle) is what ive been going by as per my later model workshop manual, so the 4 atdc figure you have and 4-6 atdc from AHH seams to agree with this.

By the way when you had your yamaha 55 how did it run at idle ? i rescued mine from a field where it had been sitting for a few years and after a fair bit of work got her going well apart from at idle ! Seams a little rough to me as in terms of vibration !!!

i will let you know how mine runs soon as i get this gearbox for it ,but when i bought it the last owner fired it up for a few moments to show me it was`ent a duffer ,but these two cyld ones are pritty noisey and vibrate more than the newer 3 cyld 60HP autolubes.
