    Default Evinrude 18HP Twinfast

    Good day!
    I purchased the above motor about 15 years ago, hooked it on the back of my 1963 Herters Alaskan 15ft fishing machine and there it sat until last week.
    I put it in the 55 gallon drum and fired it up but the gas line was sucking air and engine quit every time the gas burned up so I swapped it out for a different gas line model and fired it up and she purz like a kitten. My question is two fold. Where do I find the year and model number and how will this particular 18HP Twinfast push the mighty Herters fishing boat? She's fiberglass and heavier/sturdier than an aluminum. Is there anything else you can share with me about the motor?
    Your knowledge is appreciated ladies and gentleman.

    15 foot fiberglass I dont imagine much over 12 mph you will need a 35hp and up to hit a nice plane over 20mph.
    It takes a nickle to go first class!
    If it aint broke dont fix it!!

    It does yes! Boy it sure runs nice at trolling speed. My boat is a fiberglass fishing boat open bow similar to this. .Click image for larger version.

    I had a mariner 15 that planed out nicely...It's an open bow just for clarification. See above.
