I meant no disrespect to anyone. I simply stated fact. If the term "lug" refers to over-rev, I give merit to PSG's reply. Hopefully some day I will be a real world jet head, for now I can only dream.[url=https://www.tinboats.net/forum/viewtopic.php?p=363525#p363525 said:smackdaddy53 » 16 Aug 2014, 21:12[/url]"]Dude, if you think ranchero and psg don't have any weight on the quesion at hand you are wrong. I would second guess myself if they told me I was wrong. They are "real world" jet heads, not hypothetical ones.71Fish said:I get that .125 aluminum weighs more than .090 or .100, and total boat weight affects boat performance. I agree there are better choices of power, however the poster asked about the TS640.[url=https://www.tinboats.net/forum/viewtopic.php?p=362124#p362124 said:PSG-1 » 03 Aug 2014, 14:39[/url]"]I can't say how weight affects the performance of an outboard jet, but I can definitely tell you that it has an effect on an inboard jet or a PWC. As shown above, .125" sheet weighs more per square foot than .090" or .100" For an engine under 700cc, if you're using thick material for the hull, then it needs to be a short boat, like one of those New Zealand style jets. A 14 ft boat means more surface area, and more resistance.
My point is simply this: The engine will not lug because the boat weighs more. The TS640 will spin the pump the same whether the hull weighs 400 or 800 pounds.[url=https://www.tinboats.net/forum/viewtopic.php?p=362124#p362124 said:PSG-1 » 03 Aug 2014,[/url]"]First rule is that you don't want to over-lug these engines.
