I recently bought a 1972 Seastar with a 1972 50 HP Johnson. Engine runs well and I've learned a LOT from all of you in the last few months. Of course, a little knowledge is a dangerous thing--now I just have a lot more questions! <br />--First off--how much should the bare boat weigh? The data plate says 1795 fully loaded, allowing for six people (150 pounds each?), motor (200 lbs?), etc. Would the boat itself then weigh around 7-800 lbs? How to check this?<br />--Next, it seems that the hull is two pieces (upper and lower) and I'm wondering if there is foam (maybe soaked foam?) in between. How to check without destroying the hull?<br />--Finally, how fast should it go? I'm getting 25 mph with two people; the motor seems to be running strongly, but I don't (yet) have a tach so I don't know if I'm propped correctly, if the hull is water-logged, or if that's all I'm going to get with 50 HP... <br />--One more--how fast do you have to go to pull a skier? Don't imagine I have enough ponies for that, eh?<br />Thanks in advance, Rich
