Yamaha 70hp two stroke or four stroke

[glfisherman]

Hi

I am going to purchase a new Yamaha 70 hp. I have an opportunity to purchase either mew a 2 or 4 stroke.
Weight on two stroke is 228lb. four stroke is 260lb. The motor is going on a Seaark 1860 tunnel.

I can run two stroke in water I fish.

My question is has anyone ran a 70 Yamaha two stroke? How reliable is it. Noise level comparison?

Thanks for any input.

Yamaha 70 two strokes are VERY reliable! Yamaha's 3 cylinder two strokes were awesome. I had a friend who ran his 70 hard for 11 years without a single problem. With minimal maintence, it was just turn the key and go. I had a Yamaha 40 (also a 3 cylinder) that never gave me any problems the 9 years I had it. I'll go out on a limb and say these motors where the best 2 strokes to ever come down the pipe.

To me, 30 lbs is nothing to upgrade to a 4 stroke. I've owned several of both, just in different hp and they are both very good. Just depends how critical waite is to you, plus two strokes are a bit easier to work on, but for me, 4 stroke is my preferred.
