I searched, no defenite answer. I have a 1964 or maybe 68 90S. Its on a 17ft Crestliner explorer. I can never remember if its the boat thats the 64 and engine thats the 68 or vice versa.....<br /><br /><br />anyway....<br /><br />My lower unit is shot. needs new clutch hubs and springs and all that fun stuff. not cheap. I have the opportunity to purchase a 1966 100S with a holed piston for cheap. Will lower unit parts interchange between the 90S and 100S? would I be better off just rebuilding the 100S and using the 90S for parts? <br /><br />If it helps to determine the year of my motor (90s), it has that really funky side draft 4 barrel carb that no one stocks parts for, lol!! <br /><br /><br />last but not least, and I dont really NEED an answer on this, but it would be interesting...<br /><br />Anyone ever MegaSquirted any of these old 2 strokes? MEGASQUIRT page, incase you are unfamiliar....<br /><br />THANKS!
<br /><br />Don't forget those things need to run BRP "Premium Blend" oil and not the standard, thick outboard gearcase oil.<br /><br />I like the idea of the MegaSquirt - first time I read about it. But it seems to use a oxygen sensor for A/F ratio feedback, which isn't going to work in any 2-stroke due to the oil. But if you can set it up with a straight fuel-map...
