after class ended i started doing an engine swap in a power skiff. the skiff had a naturally asperated 3208 caterpiller with 2000 hours on the meter. the engine we were swapping in was a 3208 turbo out of a dump truck with 75000 miles on it. removing the engine took about 6 hours. after the removing the engine i removed the exhuast manifolds, heat exchanger engine mounts, and the twin disc gear of and mounted it on the other engine which took 25 hours. we also had to have up pipes fabricated and we fabrictaed our own throttle cable mounts on the engine as the one off the other one didnt fit due to the engine manifold. then we instailled the new engine and then went for a sea trial which took 10 hours. we had also installed new exhaust pipe because the old one didnt fit anymore so we welded a new one up. after the sea trial we had to remove the shaft and propeller because it was underpitched by 4 sizes. while trying to remove the shaft i found that the coupler that attaches to the shaft had corroded on there. so we had to cut it off after trying to heat it up and every other trick we could think of to get it off which to 6 hours.

total hours for job: 47 hours.
