Laser Setup Help?

777

This is my new toy, I am in the process of purchasing a 2007, 150 EFI Merc for it. It is a 18 footer with the flippin deck. I had one just like it in the 90's and put a new XR6 on it in 96. I ran a 24P Yamaha prop on that one and kept it around 5800 RPM (to the best of my memory). I was thinking this EFI may be able to turn a 25P Tempest Plus? Also where do you think I should start at on motor height?

Thanks Musky50

that motor can run about 2.5 inches below max with all the water intake holes open
but I've been plugging the top 3 and getting them up tp 1.5 below without sucking air in turns.

Is that on a Laser or Bullet? What kind of water PSI does it hold?

Is a 2007 150 a 3 liter ? what is the weight of it ? this would be my only issue. That boat weighs in at about 900 lbs I think.

Boater I am purdy sure that 07 is still a 2.5......I may be wrong. Ole bullet is dead right Musky.....gotta plug some holes on da lower and get her up. Remeber these hulls are VERY weight sensitive and they do NOT like anymore than 8" of setback MAXIUM. When ya start to prop her out what you want is a prop that doesnt lift the nose.........you want a prop that bites and lifts the stern. When ya start running the bigger numbers with Laser hulls you gotta run em flat so to speak. One prop that I know worked VERY well on a particular setup was a small ear chopper that was lightened up a little and had the Bullet Cut modification done to her. I tell ya I was VERY impressed with the hole shot of that little gem. We have a FANTASTIC prop Guru onboard that will be VERY happy to help ya out with getting her just right.....holler at Ole FAST J....da manis da bomb when it comes to props.
So tell us a little more about your ride.........By the way did that boat come from georgia??????? She sho looks familiar.

Yes id say thats where he found it, look his personal info up,Grayson Ky which is less than an Hrs drive from Huntington,W.Va(45 min to be exact)and with the boat on the water,from Proctorville Ohio.
This is called the tri state for a reason,KY.Ohio.W.Va,1/2 hr or less can be in another state.
Just about every boat ive bought had either Ky or W.Va numbers on them and lived in Proctorville Ohio.
I also worked for the state of W.Va(Marshall university-we are Marshall)
Was a member of 12 pole valley bassmasters out of Kenova W.Va,which in its final years was a Ky bass club.You can just about skip a rock from Kenova,W.Va to Ky just across the Big Sandy river.
And the only thing seperating Chesapeake Ohio and Proctorville Ohio from Huntington,W.Va is the Ohio river.
So its all in rather close proximity.

You all have done your homework on me........lol. Grayson lake is my home lake, it's a little curvy narrow 1500 acre lake. I had a Laser identical to this one in the 90's, it performed well on Grayson by being able to set it down quick turn it and pick it right back up. I sold that boat and always regreted it, then one day on craigslist up popped my old boats twin in WVA. I work in Huntington so I ran and took a look and bought it. I am really looking forward to making this one run a little better (both kids grown and out on their own) can afford to do some things I always wanted to but couldnt then. Any details you could give on some setup and props would make this little endeavor go a lot quicker. To the guy that said he worked at Marshall, I work at the steel mill right behind Marshall.

Tha tempest will be terrible on it. If your gonna run a thru hub a early model small hub Laser will work better, maybe a 23 or 25. Something that will ventilate! Tha higher ya can get tha stock gearcase tha better. A small ear (inline) chopper, even stock, will run pretty good. Tha props 1fast said are pretty good as well. But tha secret ta tha stock chopper and tha ones he mentioned is a lot higher rpm and more prop outta tha water. Dependin' on what tha added "flippin'" deck is made out of a little more bow lift prop may not be such a bad thing. We can make all kinds of suggestions but when it comes down to it, its simply "try it". We might get in tha "ball park" so ta speak but........................

BTW, Tha little small hub Laser tweaked by a good prop guy is a well kept secret on lower hp, stock gearcase motors ;)
