Set-up For Glastron Gt-160

[bobmarleylvr]

hey guys, i have a 76 glastron gt-160 with a johnson 115 V-4 and was wondering if anyone had some tips for alot of speed. I have a 4 inch jackplate that i was planning on putting on it and a custom made gas tank that is in the front of the boat (12-15 gallons). any info would help! p.s. this is my first boat

Hey There: Depends how fasy ya want ta go. Your should do about 40-44 MPH with the 115. I've got a 78 GT-150 90 Merc & it did 42 at best. I was thinking doing the same but then just went out & bought a 84 Hydrstream Valaro 2.4 Bridgeport which is designed for high speeds. The GTs are designed for under 50 MPH so you would need to do extensive mods for a bigger motor. Check out this site as It shows the Mods ya need to do. www.Carlsonspeed.com . I went though these thoughts with mine & decided to leave it as is & go the Valaro way.
Good Luck

about 2 years ago i bought a carlson gt 160. it had a merc 115 tower of power, n trimmed, i was seein 56mph @wot. what exactly are you willing to do for more speed?just simple things, or would you consider havin the heads shaved, exhaust ports bored, etc..

Hi,

I had a while ago ( 15 yrs) a GT-150 set-uped with a 140 OMC stock, a chopper OMC and i was rinning in the upper 60's with a lot of chine walking. I moved up to a OMC 235 V6 and went up to lower 70's with more chine walking but after experience, i was able to manage it ( even though it was still unpredictable.

Now i'm in a Hydrostream Project with a 2L V6 Mariner that, i do believe, has a lot more potential than the GT-150.

run of thumb is not to put the tank or any other weighty item in the front. a 115 should put that boat in the 55 mph range. with the tuned exhaust almost 60.
