las10488 Posted January 19, 2016 Report Share Posted January 19, 2016 Anyone have a top speed of the 18 CAD hull with a 150? The dealer said it was a 60 mph boat but I am skeptical of that. He also said it would do 50 with a vf115. Again I am skeptical of that. Anyone have real world experience? Link to comment Share on other sites More sharing options...
hurricane Posted January 19, 2016 Report Share Posted January 19, 2016 Might be silly question, but what do you mean by CAD hull? CAD to me is Computer Aided Design. Link to comment Share on other sites More sharing options...
linesider 159 Posted January 19, 2016 Report Share Posted January 19, 2016 CAD is non lappy hulls. The boat wont hit 60 with a 150, i dont know why a dealer would even try to claim that. And he says 50 with a 115? I dont even think the redfisher 16 with a 115 does that, and 35 hp will make it gain 10 mph? Here are the performance bulletins with the regular 150 and 115, and the boats only have 1 battery, 1 person, medium fuel. As light as the boats will ever be http://yamahaoutboards.com/sites/default/files/bulletins/bulletin_4stroke_hpv6_rel_hws-redfisher18-f150tlr.pdf http://yamahaoutboards.com/sites/default/files/bulletins/HWS_18Redfisher_F115LA_2013-06-20_FLT.pdf Link to comment Share on other sites More sharing options...
mulligan Posted January 19, 2016 Report Share Posted January 19, 2016 I do not have one but if you had it rigged for speed and not fishing you might see those numbers on a good day. The performance bulletin with the 115 is not a VF. A few hundred RPMs more might get you close to 50mph if a 115LB gets to 46. The bulletin with the 150 is the older style cap. Just going off the weight in the bulletin the new hull is a lot lighter. Not sure if it is 6mph lighter. Link to comment Share on other sites More sharing options...
Lap it Up Posted January 19, 2016 Report Share Posted January 19, 2016 50mph with a 150 is achievable. That boat will never run 50 with a 115 and normal load. Link to comment Share on other sites More sharing options...
las10488 Posted January 19, 2016 Author Report Share Posted January 19, 2016 Granted he was speaking of a vf150 and on the new layout, gas tank is moved back I think? I'm still thinking its a 56-57 mph boat naked. Maybe if you propped it for top end, but your hole shot would suffer big time. Thanks for the input guys Link to comment Share on other sites More sharing options...
lurem Posted January 21, 2016 Report Share Posted January 21, 2016 My guess is 52-53 with a 150 and 42-43 with a 115. . Agree on a price and have the salesman take you for a ride. Make a deal before the test ride, For every MPH it goes under 60 mph take $5k off the selling price. Sounds fair to me. Link to comment Share on other sites More sharing options...
M.A. Posted January 22, 2016 Report Share Posted January 22, 2016 My '14 Redfisher with a 150 Yamaha does 53mph topped out. 1 person, 1/4 tank, 3 batteries. Link to comment Share on other sites More sharing options...
lurem Posted January 22, 2016 Report Share Posted January 22, 2016 Which 150 (regular or SHO) did you go with M.A.? How do you like it? I would think the 150 would be the perfect combo for the 18'. Link to comment Share on other sites More sharing options...
M.A. Posted January 22, 2016 Report Share Posted January 22, 2016 I have the F150LA 4-stroke Yamaha. Not as fast as my old Merc EFI150, but uses half of the gas it used. Extremely happy with it. Link to comment Share on other sites More sharing options...
Drummer Posted January 25, 2016 Report Share Posted January 25, 2016 My 2000 LT18 is supposedly the same hull as the post-lapstrake RF. With the 130 2-stroke, light gear, full gas, and 2 guys it'll hit about 49. Link to comment Share on other sites More sharing options...
polliwog Posted February 9, 2016 Report Share Posted February 9, 2016 I just replaced my 20LT with a 150 Yamaha 4stroke and the boat yard called last week after testing it out and said it hit 48MPH at 6000. My boat is heavier and bigger than the 18 ,so I would guess 55 is possible @ WOT. Link to comment Share on other sites More sharing options...
bigsnook35 Posted February 9, 2016 Report Share Posted February 9, 2016 I like that you are getting that speed out of your LT. I have one with a 225 optimax that I am rebuilding. I can't wait to see what it will do. Link to comment Share on other sites More sharing options...
