470-13 mags

I just got back to my airboat after being out of town for a while and am less than happy to have discovered the engine stripped of the mags and starter. this is probably a dumb question but will mags off of a 0-300 fit on a 470?.
thanks all

I've been using the same surrette battery for 8 years and two boats, puts up with the cold and the vibrations but it $costs you.

Re: what is porpoise

porposing is usually about engine angle and weight distrabution but the bottom of your boat is also a majore factor. the bottome edge of the transom and the back 2-3 inches of the hull need to be hard and true, any curve where the water leaving back of the boat will cause porposing as well.

Re: Sprayen gelcoat

as a back yard biulder i sprayed my hull a few years ago with a 1.7 gun and didn't thin. the end result was a lot of sanding and buffing to get the orange peel out and have a smooth finish. not being a real authority i may have done other things wrong to cause the effect and i'm sure there are some ...

Re: Fiberglass hull, need poly ideas.

i can't say i know much about your hull but as for the ice we are mostly fiberglass in our area although our hull shape is quite differient. some of the newer boats being made do have poly but the transition between the ice and water and runing broken ice will be hard on any boat. have fun with it c...

Re: fuel consumtion 0-470 vs. 540

here are a few shots of the brake, mine works off a cable that runs forward working off a pedal and a lot of leverage but it would be pretty easy to set one up off of hydraulics or an electronic controller. they also double as a trim tab in the water

Re: help, need a starter for a 470-13!!!!!!

It still turns over with a lot of power but the is a pretty loud grind from the planitary setup. i thought i could get it re-wound but the gears would be pretty hard to come by.
