"Well, I just had my motor rebuilt (98 Johnson 90hp) and while I think it will be reliable for several more years to come, I still really, really want a new motor (here I am 2 weeks after the rebuild and the fuel pump craps out - OUCH. I can just see getting nickeled and dimed to death w/ electrical and "small things" over the years). I also absolutely hate the way mine sounds, smokes, etc. This also seems to be a great time to repower b/c the dealerships are all slashing prices and competition is tough. I have it narrowed down to a Suzuki 115hp 4 stroke or an Evinrude 115 E-TEC.
The pros of the Suzuki are 6yr warranty if bought by the end of April, 4 stroke, timing chain, forged crank. They seem VERY well built and my friend has twin 300's on his boat and they're very powerful and sound great. He's had no issues.
The Evinrude will bolt right up to my boat though. I just need a new tach and oil tank. I like that it doesn't need oil changes every 6 months, but that's kinda offset by buying oil to burn. I know they're powerful (2 stroke), but never been around one in person to hear how quiet. It can only be quieter than mine though - that's for sure. It has a 5yr warranty, but has to be purchased by 4/15. Also minimal maintenance - 3yrs or 300hrs. Awesome!!
The main thing that scares me is the oil injection system. I hated the VRO on my Johnson and ripped it off and premix now. What are the chances the E-TEC is going to do the same down the road?
The difference in money is $500 installed in favor of the E-TEC. I could probably shave a few hundred more off if I install myself (simple swap since most stuff gets reused), but I still have to take it to the dealer for programming. The $500 is assuming my current prop will work on the new motor though. It will definitely fit, but they're not sure if it's the right size & pitch. If I need a new SS prop, I was quoted $486, so there went that advantage. (The Suzuki is new controls, gauges, SS prop, install, etc).
