2003 vs. 2004 Yamaha 115 hp

[TADMOOR]

Is there any big difference between the '03 and the '04 115 Yamaha 4 -stroke?<br /><br />We are purchasing a 25 ft Sanpan and can upgrade from the existing '04 75 HP Yamaha 4 ST to a new, leftover '03 115 HP Yamaha 4 ST for minimal (<$1000).<br /><br />My feeling is to go with the bigger HP, but wondering about any '04 upgrades I may miss with the '03.

Rodbolt,<br /><br />Thanks for the information.<br /><br />First pontoon and first outboard purchase. We've been into performance baots for several years (decades!), guess the age thing has finally caught up to us.<br /><br />Should get the boat in the next two weeks, will let you know how it goes.<br /><br />Thanks again.

2004 Yamaha F115 4-stroke is CARB 3-star rated, 2003 model (and earlier) is CARB 2-star rated. No other diffrences as I know of. I have a Yamaha F115 4-stroke 2003 myself.<br />Get the F115.<br />/Bo

I have a 2002 115 4 stroke EFI Mecury (It has alot of Yamaha parts i.e. power head) I have also have a problem with water in my engine oil. Mercury has put a high temp thermostat and a new set of plugs along with a new ECU. It came up to about $1500 it is still under warrenty. I have been told by Mercury that up to a cup full of water is within acceptable parameters. I am currently seeking legal representation. I belive there is a design flaw in the power head on all Merc's and Yama's Power heads 115 4 stroke models. They refuse to replace my motor. I will have my day in court and then see what they will do !!!!!
