62_Kiwi Hi Nitro Boy

For manuals click on the link above called "Manuals" (always support our sponsors).

Another place to look is http://www.evinrude.com and click on "Docktalk". In there you will find how to source manuals and you can also look up the year of your motor once you have the model number.

humblechoice all models are equipped with a rubber impeller which is mounted on and driven by the drive shaft in the lower unit, water enters the lower unit gearcase through an opening in the rear of the antiventilation plate 2002-03-31

62_Kiwi Hi Nitro Boy

7518 must be the model number, which makes the year 1955. The rest is the serial number.

Chinewalker Hi NitroBoy,
Your 1955 Fleetwin is a good little motor. The water intake is through a screen in the rear of the lower unit, on the leading face of the exhaust outlet.
Most of the water exits through the exhaust, but some will come out the e

NitroBoy543 do you have any of the original spark plugs? mine all have the bar bent out of shape..., also you know the intake pipes on either side of the engien? are there air filters in there? when i test ran it in a garbage pail, i ran it for like 30 minuets, then i hosed the thing off, and ran it in a bucked wiht clean water for like 5 seconds to wash out the water intake. am i better off running it and tunig it in my garbage pail, or running it wiht a hose attachment? thanks again 2002-03-31
alcan Hi NitroBoy
The spark plugs you can get at any good auto parts store. Champion J4C is the new # this replaces the J4J. Those intake pipes are Air silencers, they are basicly mufflers. They are to make the motor more quite. They filter nothing, and unless you can see a blockage they do not require service. Making final adjustments is always done in a tank,etc. The water creates back presure you will need for proper adjustment.
