1974 20SF Rework / Modification

[PackRat]

BigLew, correct, was a straight inboard with the fuel tank under the old I/O motor box...I actually took it for ride before putting the motor up for sale and it seemed to ride fine although I have no comparison as I've never been on another 20. Maybe a little slow for RPM's/fuel compared to the original I/O or what it would be with OB - had no GPS or speed indication so would only be guessing - probably upper 20's @ 3200 RPM (1.5:1 gear). Couple times bumped the RPM's up by a few hundred and the boat really flew and handled fine but wanted to take it easy on an unknown engine. Any more details will be a mystery now....
