Rooster Tail

[CheckmatePhill]

Hey guys, I've got a '73 MX-15 with a '72 80 horse merc. I trim the motor right before cavitation, and no rooster tail. I was just wondering what you guys might suggest on throwing a rooster tail, or if it is even possible with my set up? The engine height and shaft length is all good, but I do have a stock prop, if that matters.

Thanks

KEEP TRIMMING IT THE TAIL WILL RISE

Get a chopper and raise it as high as you can

Im not sure about that one. Ive always been able to throw a decent rooster with a stock alum prop. My old Glastron carlson w/ a 70 rude would make a nice rooster tail any day. it sounds like its not getting trimmed enough for whatever reason. At speeds below 45-50, my rallysport w a 23p aluminum wont trim high enough to throw a good rooster so I have to go a little faster to do it, but A chopper prop is great for rooster tails. My sportfire w/ a 28 chopper would throw a rooster tail at 20mph or 60mph so Im not sure what to tell you.

No, it's all a matter of engine height. If the motor is too deep in the water it won't throw a roostertail even at full trim. Nevertheless, try trimming fully at half throttle and then hammering it. Most boats will give you a little something. A prop with good grip (cupped) helps alot.

Starliner with 25" Powertech TRO4, 11" setback, 2 3/4" below the pad.

What's the point in burning $10 worth of gas to throw a roostertail and not take a look?

Well thanks guys, I hope to get the chance to play around with it this weekend! Just out of curiosity, will a modern performance prop fit on the older style motor? I have been looking just to get a price idea, and I can't even find anything for the model/boat size.

only run 1/2 throttle and trim it to the sky. at the point you think it is too much........ keep going. you want it to cavitate. if you run out of trim. use the trailr button.
