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

Hi all
my next project is to build a boat it is called a ski king the recommended motor is a small light weight
4 cylinder 45 to 100 hp has anyone heard of an a15 as a inboard motor . or any other info would be great

hi lagwagon
the deck hight on a15 & a14 are the same u fit the a15 crank with a14 rods & a15 acl pistons 1mm oversize =1530 cc this will work ok with a high comp head about 29cc = about 9 to 1 comp . low comp a14 head is h72 or h75 but you can mill up to about 2 mm of to get comp up
ps a14 & a15 rods are the same . a15 pistons are 2.5mm lower but look out for crank clerance to block & oil pump
i am 97.8% on this but not 100%
hope this helps

edit get a cam to go with throttle bodies but if you mill the head look out for valve hitting pistons . (get a street cam )
or you will need more comp

i hope my spelling is ok

Hi bert
