So it’s been a while since I posted anything significant here but that and what’s happened since are stories for another time and mostly place. Fast forward to the present, my son recently graduated college and just landed a job at Lake Powell. He was thinking of getting a used jetski to explore the lake with. I ended up getting him a non running jet boat instead. Now I’m trying to restore it, quickly.
What’s wrong with it? mainly that the ecu / mpem is fried. I may send the original to Carmo for possible repair but I’m running against the clock so purchased a used one on line (it is returnable / refundable but I hope I won’t need to do that). The interior is shot and the decals faded. It doesn’t have batteries and is missing the console /only storage box. On the plus side the carbs were rebuilt last year, it was idling (on a Jump pack not a battery) when the ecu fried and the compression of each cylinder on both sides motors came back at between 180 and 210.
As for the trailer, its needs tlc as well. The tires are old and cracking at the side walls (only pressurized to 40 of the recommended 90 psi), some lights are missing and so is the connection to the tow vehicle (the seller included and mounted a magnetic set on for me to get home on). Also the trailer jack is about to die, feels like one of the gears is missing teeth. Finally the winch is shot, we found this out on the way home from the purchase, the gear the latch mates to is rusted and missing teeth and the latch is not lined up with the gear (check out my ghetto / field repair in the pics).
What have I done in the first week since I bought the boat? I washed it, removed the stereo and four speakers, starred at it a while before I started throwing more money at it in the form of purchasing parts. So far the ecu cost more than the boat and trailer combined.
Here is what I have purchased / have for it so far, aside from the ecu:
Upholstery skins, Hydro turf / blacktip deck mats,
New decals, batteries, Marine Stereo and four speakers,Towable cover, Storage compartment,
Four popup cleats and grab bars from a Yamaha jet boat, yellow paint for plastic and 3 gallons of xps 2 stroke oil.
For the trailer I got:
A new winch, trailer jack, lights, guide posts and self retracting transom straps. I haven’t got new tires yet as I need to research how much larger I can go on a 12” rim.
Attached are some pics





I will add more pics and update the status as it changes.
