If I had the jing for a Fla. (or Lake Erie) "day boat" it would be a mid 30's center console.
Some of the stuff I used to see being built down in Miami was incredible. In my mind they just do everything really, really well.
I remember one of them telling me they were working on a mid 40's boat for same. I always thought that was the perfect way for you/friends/family to get to your vacation home in the Bahama's on the weekend.

To be honest, upper 60's. The engines were 300's but I doubt they made more than 250 as they had a questionable past before I bought the boat.
What it did do though was produce an easy 55mph cruise at 4800rpm with 8 people and full fuel. It was also very good in the rough stuff for a 32. I did lots of engine mods, ran them high on the bracket and used Bravo 4 blade 24's, very nice reliable set up. It was pre-GPS so I never really knew what it did wide open, I go the cruise speed from time over a known 28 mile run.
Making the v8's run without breaking was one of my finest achievements!

One of the most under appreciated, under developed O/B's ever built.
I kinda like this old ad. Note HP rating,operating range, carburetion, weight (comparable w/current 6's) and fuel quality spec. Remember, this was mid '80's and pre computers etc, etc. All from 3.5 liters too when most of the current V-6 4 strokes are at 4.5 after 30 yrs of development!
Pretty impressive stuff and an example of what was there if you knew where to look or where to go to for help.

We went through about 20 of them in 5 years! Tough learning curve that was, one day Carl Sandstrom from OMC came to see my boat and liked what I had done with the engines. I basically took all the vro's and stuff off, over jetted them and used an external fuel pump. The engine blocks looked naked without all that stuff on them but ran sweet.

Knowing quite a bit about the 8's myself, that is a hilarious (though painful and expensive) statement.

Here is my last V-6 I went Gonzo with.

The "twin pinion fully shiftable gearcase" is the wholly grain of lowers for OMC V8's. Most of them ended up in Middle East.
Rick from OMC engineering department wanted my powerheads because to date I have not had a powerhead failure (knock on wood). I still use the VRO pumps. I do premix because of race use.
