Keep the engine and transmission cool
I pulled by Catalina 22 for years with a Ford Ranger, 3.0 liter, auto trans with 243 rear end standard cab. This was done here in the western Pennsylvania mountains.
I installed a engine oil and transmission cooler. The oil cooler used a larger filter and was relocated on the frame adding over 2 quarts to the oil system. My boat is always loaded with more stuff than the average, so the weight would be close to the 26x. I’ve pulled it up hills in the range of 6 to 9% grade for a mile and half at 15 miles an hour without the temperature gage moving. I though about changing the rear end to higher gears but with never having any problems I never did.
The truck was small so I never pulled over 55 miles an hour and keep the speed down to 40 to 45 when descending hills.
