Re-power haines v16R

[Maximum]

There has been a lot of discussion on the forum about the 'new' Yamaha 70 4 stroke. Given the light weight of this motor it seems to be a good option for repowering the older glass boats which weren't designed for the heavier 4 strokes.
My 16ft Haines has an early 90s model 90hp evinrude which has been an excellent motor but getting a bit long in the tooth - I'm wanting to take my 4 and 6 yo out and need something reliable. The hull itself is sound as the transom was replaced professionally a couple of years ago. If I get a new motor I will work towards putting it on a new hull one day.
My question is: will the Yamaha work with this boat? Has anyone tried this before? Intended use - cruising inshore and maybe some tubing and wakeboarding. Our 90 can pull up a slalom skier and I accept this wouldn't be possible with the 70. Many of the older Haines boats seem to have big HP - I've seen boats like mine with 140 but my 90 seems plenty quick. Is this because of the deep v or were people just bigger hoons in those days?
I saw a report with a 70 Yamaha on a 4.8 cruisecraft and it was heavier than my boat and went fine. Any advice would be appreciated.
Thanks

I repowered my 16r with a 70 zuk 4 stroke. It was a bit heavy in the arse but the boat worked well with it, I never tried taking skiers. You'll have to be careful that you buy the right motor that will go on the next boat. The 16r has a 20" leg and a lot of boats now are 25".

Hi thanks for that Jarrah Jack - just what I was after. From my understanding the yamaha isn't as heavy as the suzuki - I think it will be about the same weight as the evinrude. I didn't think about the 20 vs 25 leg issue so will bear that in mind.

If you get a 25" you can always put a jacking plate on the 16r seeing the transom is good. It gets the motor that 5" further out of the water which isn't a bad thing at all.
