Nissan/Tohatsu goes so far as to put in a water pump for cooling ... but STILL no external tank option :-( !! dave scobie M15 #288 - SCRED visit Scred's www-site: http://www.freewebs.com/m15-named-scred --- On Tue, 8/12/08, Paint4Real@aol.com <Paint4Real@aol.com> wrote: If 2 h.p. seems too little/risky and 4 is a handful, look into the Nissan/Tohatsu 3.5 4-stroke long shaft, an in-betweener. It weighs in at 43 pounds -- just about the extra weight I'm carrying around every day (gotta do something about that.) Whether to go to 2.5 was settled for me, because I wanted a long shaft and only the 3.5 had the option. The 3.5 sold new for only $44 more than a long-shaft, air-cooled Honda 2 h.p. Almost twice the power for forty bucks. No contest. Steven "Shenanigans" M15 #324
