175HP Sportjet Dry Stacking
Hi I have a 175 Sportjet. I have heard that the exhaust is very restrictive on this motor as it is the lowest output of three models with the 2.5 block. The higher HP motors exhaust through the hull via mufflers where the 175hp exits through holes in the Jet pump casing. I don't know how the cooling water flows through the heads and block but do know that the water exits with the exhaust. Does anybody know how to and if it's worth dry stacking this motor? The 210hp motor looks to be the same as the 175hp other than the through hull exhaust, a 25 to 35hp gain would be worth while. Thankyou.
