| I'm asking because it is much lighter (253lbs) than the other motors in it's "sub 90hp" class.
I currently am running an older 75hp (1990) Mercury on my Newly rebuilt Tuffy Esox LTD. I like it and it works great, but, I rebuilt my boat and now I want a new motor.
It's hard to make this change because my existing motor is bullet proof and I've always babied it. That being said, it isn't a 4 stroke, it has that blue smoke that is noticeable when trolling with the breeze, uses more gas than the new 4 stroke will, is too loud for a phone call. (I'd like to work more from my boat, ie phone calls, etc..), and vanity wanting a new motor.
Here is what I've looked at: All motors 70- 90 hp because 90hp is my Max rating. Here is what I found: Mercury, Yamaha, Honda, Suzuki 75's-90 hp motors all weight in around 360 pounds. My current motor weights 299lbs. I'd be adding about 60 lbs for any of those options. One of the things I found I don't need this summer is top speed....I thought I did, but after the last full season, I realize I don't need it as one of my top 5 reasons.
Yes I looked at the Evinrude as well and that motor in a 75-90 is about 320lb.
I've settled on the 70hp Yamaha for these reasons: ,
1. weights only 253 lbs, vs mid 300's for most 75-90hp motors
2. similar in actual hp to my existing 29 year old 75 hp motor, especially with motors now being rated at the prop rather than back then at the head. My current motor does a great job running my boat by myself or loaded for a week with one or two others in Canada for a week.
3. quiet and very little vibration compared to other motors.
4. Fuel efficient, excess of 8 mpg at my cruising speed
5. trolling feature adjusting down to 50 rpm.
Top speed variance although not known: currently I top out at about 38, cruise at about 30. I assume that would be similar with the Yamaha F70. I'm guessing that I'd up my top speed to about 43 with a 90 on the back, cruising at plane about the same.
What am I missing? Any input or experience from anyone out there?
Thanks,
Kevin
