Re: Evinrude Model 4434
4434 is a 1950 7.5hp Fleetwin. They've got the flyer for that year over at
www.oldomc.de which has most the info on it. <br />Other specs I've got around (in addition to DHPMARINE's):<br />Plugs: Champion J6C (was J6J)<br />Fuel/Oil mix: I think this was origninally 16:1, but revised to 24:1.<br />Price: $190.00<br />Lower unit fluid: 90 weight outboard gearcase lube.<br />WOT rpms: 7.5hp@4000 (3500-4500)<br /><br />The 7.5 had a bit of a reputation for throwing connecting rods, which went on to breaking holes in the block. Go no leaner than 24:1, and never rev the engine in neutral (ie, don't abuse it), and you should be fine.<br /><br />Anything else you're after?<br /><br />Also, thanks for posting the Lightwin owner's manual. That was very interesting reading!
