My repair manual states - To check the maximum <br />spark advance, the outboard MUST be operated with the proper test wheel. DO NOT operate the powerhead with a propeller, or flush adaptor while performing this adjustment. Indicated to <br />connect a timing light - operate powerhead at a<br />minimum of 5000 rpm with the outboard in FORWARD<br />gear and align between the 18 and 20 degree mark.<br /><br />I have synchronized all the linkage and the motor<br />runs and idles great. The best ever!<br /><br />My top rpm is low. Top rpm is about 4800, book<br />indicates it should be 5500 to 5800. When I was<br />fooling around (I mean being very foolish) I changed the throttle and spark control rods. <br />Would not idle well, however my rpm under load<br />would reach over 6000 rpm, felt this was bad -<br />went the the manual synchronized throttle and <br />spark rods etc. That is where I am at present.<br /><br />I use the motor on a 21' pontoon boat.<br /><br />I can live it's present preformance, however would<br />like to know the timing was to spects for fuel<br />consumption etc.<br /><br />Can I purchase a Test Wheel or does anyone have<br />a better solution to subject wheel?
