With the help of many hours of searching your archives. I bought this old but clean Tidecraft fish&ski with the Evinrude. It ran well but had sat awhile indoors. My first real boat with a wheel not a tiller. Here is what I did.
Took apart thermostat housing cleaned it up, oiled it made sure it worked in hot water.
New hoses.
New impellar.
Changed lower unit oil.
I found something about the deflectors in the heads. I got some 3/8 fuel line and replace those.
New spark plugs
New fuel filter.
Last but not least I used Dunk's seafowm method 3/4 gallon gas, oil, whole can seafoam etc.
I also had to adjust the throttle and shift cable. As it was throttling up nefore engaging forward and slamming.
Ive had it out several times now running it hard. It runs like new. Bump the key, perfect idle. No hesitation when you nail it. Cruises 40mph pretty easy. Thanks for the help.
