trailrat, I have a 175 sj in my 19' Thunderjet and have no problem with power. Gets up on plane pretty quick with 4 adults and fishing gear. Did have a little problem with smoke the 1st year but that was solved. I put some insulation (1") made to quiet inboards in my doghouse and it made some difference. I do have the stompgrate which works well clearing debris although I have not had the pump intake plug yet. All in all I like it very much, comes out of the hole well, 44-48 mph depending on load and the accuracy of my speedometer, handles very well. Good luck
