1991 Sea Ray 160 w/100hp

[TenE307]

Here is my situation, i am wondering if it is correct.<br />I just purchased the boat. I came with a 19 pitch prop, changed to 17 pitch.<br />the two props act about the same.<br />The boat acts fine with two people in it.<br />can get up on plane and goes about 30 at 4300 rpms.<br />When i put four people in it it doesnt want to let me get on plane, and goes about 26 mph.<br />Will be getting carbs rejetted soon for elev change.<br />Is this as fast as this boat should go.

TenE307,<br /><br />MPH means very little in a boat as far as proper engine set up.<br /><br />Your engine should be capable of reaching it's maximum wide open throttle rating with a light to moderate load. If not, you are lugging or overworking the engine.<br /><br />If altitude is an issue, get the engine rejetted, as you mentioned, then go after the proper prop.

Thanks for the info.<br />does rejetting make a big difference in engine performance.

I owned a brand new one of these boats back in 1990. Mine would run well into the mid 40 mph range with 2 people and a medium fuel load. I do remember it slowing down quite a bit if the bottom wasn't kept clean.

What is the rpm at wide open throttle? You mentioned 4300 but not if it was WOT.
