I would trust the paperwork on it: looks to be pre HIN era (earlier than 1972). So, no real telling what it is. Could be a Sears hull; there were several manufacturers.
1832, 1859, 1884, 1973, 1980, 1997 ...
I'm not opposed to electric cars. There are a few that seem pretty slick. But, I don't think the whole of transportation is going to go completely electric; including cars.
Do a little readin' over the restoration forums: I can't find a topic at the moment that's a mirror for yours. But there are plenty very similar.
IMHO: to do it right, you're going to have to pull the top cap off the hull (disconnect at the rub rail seam), clean out the deck, put in new...
Welcome aboard.
Inland lakes? Big lakes or smaller? What type of cruising? Just you and a pal? Wife/girlfriend? Or are you taking out a whole party of people?
Those types of questions will help the bunch of us make better suggestions.
Start a topic for it in the rebuilding forums. If you have photos from before you stripped out the deck and the stringers post 'em up there.
The side pieces along the bottom of the gunwale were mostly for stowage. I think your stringers in that boat are all under the deck (not too much side...
More history than present. Several people have tri-hulls, but the old types are kinda' dying out.
Yours looks decent. What kind of ideas are you lookin' for? I may be able to point you to some projects I remember.
HA! I'll never get it done. I can't believe how busy I am these days. Not to mention I'm in the 3V club on a visitor's pass: I wound up getting rid of my tri-hull a few years ago.
Bummer that Red is over on Facebook and not here anymore.
You likely won't find one online. Those types of things aren't published normally. However, if you contact Mako they "might" be able to send you something to help you see the layout.
I'd say pull the boat, get it nose high on the trailer and see if you get any water dripping for an extended...
If the boat had been running normally up until the impeller change (as in it hadn't sat for years), then that would be my first suspect - either something was done wrong, or the aftermarket kit didn't work right.
Can you test water flow up by the thermostat and make sure that you're pulling...
Welcome aboard: are you sure the impeller is installed properly? (Start with the basics, right?) - I'm assuming this is a boat you've replaced the the impeller before?
Boat manufacturers typically didn't/don't publish any sort of significant manual. So, it's not unusual to find one.
The motor will have plenty available though.
