Are all 2 stroke 15HP Yam's much the same

[TomKat]

Looking at a tidy one locally and have no idea of the model history, are the old ones as light and portable as the more recent ones?

just got a pic sent to my phone, looks something like this one though not as scruffy

yamaha 15hp enquiry - Practical Boating Forums, marine forums, sailing forums, boat repair forums, inland waterways forums

looks a lot taller than the type I have seen before, does that make it heavier, the height to me looks like its all in the recoil assembly but not too familiar with these engines so any tips appreciated. It is at an attractive price so might be a cheap engine if it is similar weight to the more modern units. May be able to put an actual pic up later.

It is a model 15A serial number 651.S01693 if that helps anyone?

Your serial number puts it at 1974/5

Sorry no specs, just a parts list.

A classic then! Think I will pass and get a newer one over the winter as I want it for next year. Relatively cheap at £400 though...

This is a pic of the actual engine, how would the weight of this compare with the more modern engines? Pretty much decided to leave it but if it is mechanically the same and only cosmetically different that would make me reconsider. Any thoughts?

They were a good very reliable engine , I bought one new in 1977 also had the exact same engine that ran on kerosine too for a fishing boat I had .

bit on the heavy side though ,I used it on a Zodiac 10 ft 6 inch sib on a regular basis during the summer months until about 1990 and only sold it about 4 years ago ,
in all that time it never broke down and always started on the 3 rd pull,
Down side was that the prop has a sheer pin instead of the the modern style hub and after a while the pin hole started to get worn and became elongated no problem as the prop slot had worn too I just reamed out the hole and went up a size sheer pin .
It also only ever had one new set of ignition points changed in that time.
A good reliable engine if a bit of a heavy lump but I'm not too sure if I would part with a load of money for an engine getting on for 35/ 40 years old.
I still use an stripped out powerhead /engineless model for one of my old y boats when used as a display boat for Rnli events especially if we are doing a long distance boat pull .

Thanks, pretty much what I concluded, an OK engine but heavier and poss not to be trusted as much as a more modern unit. I really only want this for use with a SIB for some calm coastal trips with the family so must be reliable and easily transported in my camper. Dont need one till next year so can keep my eyes open for one over the winter.
