On my Force 50hp the compression reading I am getting even on both cylinders is 90 psi (hot & cold). I have used 2 different compression gauges to test with and get the same reading on both.... They ARE Harbor Freight gauges so that may play a factor. I have read many reviews on Harbor Freight tools, where the specs of the tool say a way higher capacity than the tool can actually reach. Also re torqued the head and same exact 90 psi. It seems to be running fine. This is the only Force 50 motor I have had so I have nothing to compare it to. So I guess my question is, is if my compression really is 90 psi on both cylinders... will it be reliable enough to take out to the lake and not worry about it? If so how long should I expect it to last? And is there any other ways I should test the compression to get a higher reading?
