Look I love your enuthiesium on this project but its over 30 years old and you might want to play it safe and pull the motors and send them to a local shop to get freshen up. Remember the goal is a reliable boat that you can enjoy. Sorry to be negative, but I know for a fact that buying gas is actually the cheap part of owning a boat.

Good luck

got the heads off the starboard motor and still can’t figure out why it’s only moving 180 degrees. Got a couple different options to get the motor pulled out so time will tell what the issue is.

Finally made some time to get the engine pulled and tore down. I live in Michigan so I’ve got plenty of time this winter to get it ready for spring. Next step will be to deliver to the local machine shop.

Hows this project coming? what was making the engine only turn over 180 degrees?

hey Kreed, been plugging away on the motor, cleaning up the internal parts and cylinder heads. It was hung up on rust from the bottom of the cylinder wall in #7. I have some time off work coming up, looking to start reassembling here in May.

Slowly getting it back together, I really thought I would have had it done before July but everything seems to take me three times as long as it probably should. Got my son involved cleaning up the bilge.

Just like any project around the house.....my wife always takes my "estimate" and doubles the time and triples the price! LOL :D

Got the motor dropped in and topped off the gas tank. Need to hook up all the electrical, accessories, exhaust and get the drives back on.

Got it in the water tonight. Didn’t get to really do a test run I really just needed it off the trailer. Got an appointment to get new tires for the trailer in the morning.
I still have some work to do on the interior, really just need to get the backseat back in, the wall it attaches to and the front cushion on the engine hatch that my wife restitched the seam on.

it needs good cleaning to…….its dirty from all the work it’s taken.

Got about 15-20 hours on the boat. Been idling up and down the lake. The rebuilt motor has been issue free however the port motor not so much. The port motor at first would only run for 5-10 minutes and quit. Then after a while and it would run for upwards of an hour putting around with out issue. Tried to get the boat on plane and the motor spit and sputtered. So at this point I’ve only gone as fast as 7ish mph. I have not done anything to the carbs so I was going to start by rebuilding both carbs and go from there, seems like the most logical place to start as I believe this is fuel related, but just guessing at this point. This adventure has no end in sight 😁

What do the distributors look like inside ? They clean and rust free. ?

swellcraftman 08-26-2024 07:58 AM

Ahhh the one I took apart looked great on the starboard motor…….. good call that’s something easy to check I’ll look at the port motor tonight.

Looked ok to me? I went ahead and switched the cap, rotor and plug wires on the motors to isolate the issue. Ordered the carb rebuild kits tonight.

Boat is running good enough to crawl up and down the lake. Pumped some water out of the tank and just cleaned the carb so hopefully that gets me on plane. 😁. Spent a couple days rubbing on it to try and bring back the shine in the gel coat. Got a new set of power play stickers for the boat, I went with white reflective and the original size. Thinking next year replacing it with a larger size and possibly the old school powerquest logo.

jeff32 06-13-2025 04:30 PM

good to see its getting some love !

swellcraftman 06-14-2025 08:33 PM

Pretty exciting day, the boat got right up on plane today. I only had it there for a minute as Spring Lake has no wake for 26ft and larger. Next weekend I’ll hit the Grand River or Lake Michigan to hit cruising speed for a little longer.

NC03GT 06-15-2025 06:50 AM

Definitely looks like the boat cleaned up nice!!!

swellcraftman 07-14-2025 07:25 PM

Spent Saturday rebuilding the carburetors, definitely a task that was over due. First time rebuilding a carb, I’ve always monkeyed around with carbs on my dirt bikes but this was definitely a bigger job. Going to test it out later this week then hopefully get out to Lake Michigan this weekend to check out the poker run out of Grand Haven.
