    Securing batteries in Supreme trout boat

    Boat Manufacturers should be required by Law/USCG, to engineer a Battery Hold Down Location where there is enough Structure to securely secure Batteries without risking going thru the bottom of the hull. A couple of r/8" long #6 Screws going into a 3/8" thick Plywood, isn't much for a 30lb...

    Boston Whaler Prop

    Welcome to iboats Sounds like you can drop down a bit in Pitch, which will raise the RPM and improve the Hole Shot. If the tach is accurate, you are quite a ways from the 6K limit. Even though with less Pitch, which you are likely thinking, lower top speed, the engine will be running nearer it...

    Anyone Seen these?

    I don't know if it any good or not. However I fed up of one Test Site which has been trying to promote that thing, like an Infomercial. Only things missing are Mike Levey and his sidekicks Ian and John. That site has never reviewed an item that is supplied by their Advertisers as being less than...

    Building a wake boat.

    your idea of Large Waves close to the Shoreline might destroy the Nesting Areas of many Species of Birds. For that reason alone, I know my country is looking at passing Laws to prevent Wakeboard Boats being operated closer than 5 miles from any Shoreline. Really Needed and long Overdue

    Battery questions - Winner with 80 HP Johnson

    Keep in mind it is a 55 year old motor, and even after any repair/parts replacement, it is still a 55 year old motor. Have you checked to see if there is Oil and/or Water in the Gearcase? At minimum, it is going to need a new Water Pump impeller, New Gear Oil, Carb overhaul, and Ignition...

    Battery questions - Winner with 80 HP Johnson

    Electric Start. An Electric Shift model would have Electramatic in that location Very little, if anything, in that Manual will be of much, if any use to you. Totally different Carbs, Ignition Systems, Midsections, Lower units, even Throttle Linkages. In 3 words, totally different engines FWIW...

    Mariner 1977 - 80cc help :D

    Welcome to iboats Your engine is either of the 1968 thru 1972 vintage, or 1978 thru 1983 vintage. The Grooves/Knurls on the Piston Skirt, are post 72, so I suspect your engine to be in the Latter If the Cylinders are scored, you should address that, as it will just get worse. Looking at the...
