    1969 IMP "Thunder" 20 ft, Restoration

    MAY 4 Update Last week I got the engine running. The issue has been bad gas. Dirty gas that plugs up filters, and takes out fuel pumps. But I saw no way of removing the gas tanks without cutting the original fiberglass structure. Not a good plan. Then I started removing some of the beauty...

    Genius! I was thinking of ways to wire in a primer switch. This solves the issue in a workable and easy way!!

    1966 MFG Rebuild

    Like the man said,"There is never enough time to do things right the first time, but always enough time to do them over again." -Grin!

    I saw that option in the instructions. Sorta defeats the point of running an electric pump if you need oil pressure built up BEFORE it will pump the gas. ??Would they have a problem with a Priming circuit?? A push button to run the pump momentarily until the fuel system is fully charged? The...

    I've seen plywood in 5 places. All minimal in size or structure. Everything is fiberglass.. even the floors are fiberglass under what remains of that blue carpet. I took soundings for de-lam and found none. the covers over the bilge(?) are plywood. There are two more that serve as lids to...

    Piston Rings don´t fit, too little clearance, sits too tight

    I think your best (not cheapest in the short term) option is to buy both piston and rings from same source to ensure a proper fit. Then check end clearence to be sure. Also - align rings so the gaps are 180 degrees away from the next as they sit on the piston before installing them. That...

    1969 IMP "Thunder" 20 ft, Restoration

    April 5th, 2025 The weather has finally started cooperating. I have made some significant progress, where first step are concerned. Everyone said to do a compression test before investing too much in this project. I got that done. [COMPRESSION TEST] All six cylinders are firing on 120 - 145...

    iBoaters...Where are you!!!! - Members Map

    My pin added in Nampa Idaho. I only see three others within a two hour drive. We are rather spread-out in the West.

    Prop Selection - Bayliner 175

    Sounds right. But it is uncommon to have such high numbers. Your scale may be off, uncalibrated. Gas burns in the 50 to 90 psi range (typical) higher readings on a racing engine or a diesel. I like to 75 to 80 psi when I'm testing

    Don't know what I got

    A boat is not like a car, and neither is a Jeep (4X4). It occurs to me that they have one thing in common, well at least they do here in the wide open western states. You see, if you take a Jeep out wheeling, and you've driven about an hour or two into the wilderness, if it gets stuck or broken...

    1969 IMP "Thunder" 20 ft, Restoration

    I recall reading somewhere that the older fiberglass boats did not use wood. They are all fiberglass. This is a 1969. Could I be so lucky? I've checked everything, and it all looks, sounds solid. No delam, no rot, no separation so far. The floor isn't even spongy or anything. So I found...

    Don't know what I got

    (( I knew a Captain in the AirForce, who said, "the definition of a boat is: 'A hole in the water, into which one must throw a lot of money.' He was building his second sail boat at the time. He had lost the first one to a sand-bar collusion.))

    Engine cranking not catching

    My bad. But my point is still valid, compared to old school carberated and running around 4 psi. True?

    In need of electrical help

    Wiring issues are often fairly easy fixes, but there are too many what-if's right now. Start, always start with checking for a good ground. Then follow the lead from the batteries positive connection and look for power where ever it is attached to. If there is a relay in line, one side is...

    Engine cranking not catching

    Boats run on water, but engines don't. Water in the oil is concerning. About how much water? And, what did the oil look like? Options are, clean like honey, and new. Dark black, or milk chocolate brown. If the plug that was leaking was a freeze plug, do the test on your cooling system as...
