I have a XR2/SST (depending on who I ask it seems) power head for sale.
Compression is 145-150 across all 6.
It will be complete with either elec fuel pump (what I used) or I can supply the stock crankcase driven pump (rebuilt, but not used as I used the elec one)
I have some videos of it here:
compression check -
Couple of points It will be supplied as a bolt on and ready to go power head, with merc stator and switch boxes, and choice of pump. The velocity stacks and prop are NOT included.
It is currently on a 20in leg, with older style V6 gearbox and internal transom pump (leg is from a 79 150, and gearbox from a 200, 81 iirc)
I have run the engine for the last two years without issue. I have done about 50 hours on it, with it bolted to my 17ft Fletcher.
Power head alone im after £1250 ono.
Complete as it is I will accept £1600 including pump/controls, cowling etc. You will only need throttle cables/prop to get it to run unless I have the ones you want already (I do have a few lying about) I will also include another gearbox which is fine going forward but slips dog teeth in reverse.
Drop me a PM if interested.
