Dave, I don't know why a choke would be necessary, as their purpose is to enrich the fuel mixture until the engine is warm enough to vaporize all the fuel droplets. Propane is of course already a vapor at boating temperatures (unless you are boating on Mars, which has some other negatives). As for the 12-15 pulls, that is equally puzzling from a physics perspective. I wonder if other folks have this problem. Glad you brought it up for discussion.

i don't recommend a short-shaft outboard on an M17 ... cavitation city! sadly, the LEHR 2.5 is only available in a short shaft.
glad you like your LEHR Steve. i'm not fully happy with the one Sage Marine purchased -
poor fit/finish, doesn't run correctly (not running up to full RPM), difficult to start first time (when cold or just after installing fuel bottle 12-15 pulls required), no choke (is needed for a cold start to keep motor running until warmed up), and no fuel cutoff.

I switched to the Lehr 2.5 propane aux power for my M-15 last year. It should have plenty of power for the M-17. I haven't used it much yet but been happy so far. No hassle with winterizing or gas spills. It only has F-N so it requires a 180 turn for reverse. I was concerned about this but it hasn't been a problem.
