Need help beating dead horse, '73 20' Repower

[esoxesox]

Hi Folks,

I have read and reread posts discussing Etec G1 150 and Suzi 140 for repower but still am waffling on which one to go with and could really use the thoughts of the folks here.

My Rig:
'73 20 CC
'95 Johnson FastStrike
'12 Yamaha T8 kicker on port corner
Replaced transom 15 years ago but just did to 20" again (yeah, I know better now).
Planing speed around 18 mph
Top end around 47 mph
Renegade Offshore 17"
No tabs but plan for Bennett Bolt with engine install

I run on the Great Lakes, commonly running 30 miles in a day chasing temp breaks or mudlines. Also take the rig remote camping now and then so loaded down with gear for a week in the islands. I don't go full throttle all the time but like it when I need it to beat a storm off the lake. I know the Suzi probably is the better choice for long term service but I am very concerned I'll be disappointed with the performance going from my existing set up to the 140.

I've reviewed the Suzuki Performance pages and the numbers are all over the place. The stats on the Blue Wave Pure Bay 2200 on their site look great with 17/49 planing and top end but a bunch of the other smaller boats show top end ~42.

The BRP performance site is a PITA. I can't even work out a similar hull they've tested with a G1 on it. There are a couple on Ranger, Stratos, etc that have good numbers but, again, some of the numbers on the smaller aluminum hulls are not super different from the Suzi 140.

I wish to beat hell there were a way to demo engines on boats but, as there is not, I am hoping the knowledge that resides here can help out. I have a line on a new G1 150 for about $2500 less than I could get a Suzi 140 installed for. Cost is a factor but performance concerns weigh more heavily on my mind.


Thanks for reading the ramblings. Any thoughts would be appreciated.
