I've recently picked up a 92 ProCraft 180 Dual Pro w/ 150 mariner Mag III(Bass boat). Took the boat out yesterday to the lake for the first time. I was given a few different props with the boat. The prop that was on it is a Mercury Trophy 13.75" 21p. The lake I went to is about 5,000' in elevation. My question is, what should I expect to be a normal time for the boat to plane? With the prop mentioned above it took about 7 secs with 3 adults in the boat. I put the other prop on, I'm not sure the size ( High Five), and it shaved about 1.5 seconds off. It also has a hydrolic jack lift on it too. I had the jack all the way down w/ trim all the way down out of the hole, after the boat would plane, I trimmed up but left the jack down. I reached around 5,000 rpms, but never topped out to the wot rpm's of 5600. The other question is for the few occasional times my kids might want to go out, do you think this setup will pull a tube around. This is my first boat. Thanks is advance for your input....
