well i have seen a a12 in a smaller tractor.

thought front the title it was an a15 in a skyline lol

I am on a steep learning curve wen it comes to marine inboards it seems that the motors specified for the boat are from the 1950s the top of the range ford V8 only 100 hp but 180 ft ponds of torque. so a 4 cylinder 50 to 100 hp but these motors were low reving larger capacity heaps of torque. so i might have to reconsider tha A15
i cannot find any info. on a15 torque .
i found info on L20b but 100 hp seems low
is this right . L20 is a better choice but is it the way to go .
hopefully you guys understand what i am on about.





[edit] L20B
The L20B was a 2 L (1952 cc, 119 cu in) engine produced from 1975 through 1985. It produces 100 hp (75 kW) in 1981 form with 112 lb

my mate has a alloy boat approx 10ft with an A14 in it, it's jet powered, i don't know if he has it running yet, he was chasing a carb for it.
