220 GPU runs great!!!

Post by jopete »

I've been on here for a few years now, and most of the time the only thing I read about gpu's is when they have problems.

thank goodness for the folks like John Fenner and GMAC76, along with many others that I am sure need mentioning but I am forgetting.... who timelessly answer questions and help folks.

what I am posting about is the fact that I run a little 12' gpu powered boat and it's a battleship. I love the thing. it doesn't leave me in the swamp unless I sink it or stick it where I shouldn't of gone. of the 5 airboats I've owned, it has been the easiest to work on and find parts for. [starter and alternator]. I really like the 1 mag and the holley 500 carb. it only throws/burns a quart or 2 per 30 gal fuel tank, and oil is cheap. i don't have a 'hill' to run, but i can run dry and cross levees and such without issues. in this time of hp crazy boats and everybody going car motors, it is awesome to me to be running my gpu. if it ever fails, i'm going to rebuild and get another decade out of it!!!!!

cheers

btw, my avitar is a closeup of my blue heeler Dude trying to smile. lol

an FAA/PMA rebuild kit for that mag is crazy expensive ($250 to $650) depending on which kit ya need for which mag your rebuilding....in my shop a complete rebuild.bench test, gasket and shipping for that mag is $185 or a complete mag ready to mount up is $300 and your mag if rebuildable and complete is worth $50 core

Ryan if you look through the past postings on here via the search engine you will find GMAC 76 has helped out a lot of folks with their mags being redone over the years for a very fair price.

Achilles heel of these engines is the thrust bearing, they were never designed to spin a prop.

Lacy Everett x 2! He rebuilt my entire motor and it’s tight and leak free with great compression. Nice people too.
