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.

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

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

well i have seen a a12 in a smaller tractor.

I'm finding it hard to believe someone at some time created a marine manifold for Datsun A engine... but seeing is believing.

I saw the water cooled manifold a while back, I think it was on ebay, i missed out on it though...

so there must be the odd one about...

like this manifold.
do a search on 'boat' you will find all you need.

there was someone on here ages ago with a a-seires in a boat who needed help with somthing engine wise(i think they wanted to know how to get more power from there a-12??).. one perticular thing i noted is that they had aftermarket water cooled manifolds(not custom ones!!!) so they must be used by some group of boating people out there to warrant enough to produce the cast manifolds. ive thought many times about putting a a-series in a tinny..

Haven't seen a A-series in a boat but i've seen a Hilux diesel engine in a yacht.

No reason why it wouldn't work, should work pretty well in fact!

Keep us updated with the progress!
