Suzuki DF timing belts or chains

[lmcmullan]

I am about to purchase my first new boat and need advice regarding the outboard. I am getting a 18' custom aluminum CC jon pushing 800lbs+ dry. I have decided on the Suzuki 4s line based on price and EFI. The DF60/70 have timing belts versus the DF90/115 which have timing chains.<br /><br />1.) Do the chains require less maintenance? A buddy told me belts must be checked/changed once a year by dealer.<br /><br />2.) Is the DF90 more fuel efficient than the DF115 since they have the same block? The tests posted on Suzuki website were not very helpful.<br /><br />This boat will be used to hunt and fish so I am not considering a 2strk or carbed O/B which I have found to be quite cold-blooded when duck hunting.<br /><br />Thanks,<br />FurDuksNFish

Howdy, fur. . ..<br /><br />The DF60/70 timing belt is recommended for replacement at 400 hours. Tension MUST be adjusted exactly as instructed in the manual. I know of no belt failures.<br /><br />The twin cam Suzis use chains, which are a bit noisier but require less maintenance. Tension is adjusted automatically. Replacement is much more expensive than the belt.<br /><br />The DF90 will not be any more economical than the DF115 at the same speed with the same boat.<br /><br />I love my DF70, and see no reason to buy a DF60 or DF90 over the DF70 or DF115.<br /><br />Good luck.

Appreciate the help guys. <br /><br />Since there's not that great of a difference in cost I will splurge on the F115. Figure I can haul quite a load with taht compared to the lower models.<br /><br />Take care
