I apologize first off if I've put this in the wrong section, but I wanted to hear this from the guys who are more likely to be experienced in this area. I've recently picked up a 92 ProCraft 180 Dual Pro w/ 150 mariner Mag III. 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. This is my first boat. Thanks is advance for your input....
