New Fountain Owner
 

Hello from the West Coast.
I have been a member here on OSO for some time now, previously owned lots of boats form 50' sportfisher to my favorite which is my canoe. I owned an older Scarab and that's what brought me to OSO to begin with. I currently own a 21' Howard day cruiser and most recently bought a 1989 Fountain 33' Swim Step, which I believe was shortly re-named the 35' non-step. Please correct me if I'm wrong.
I found this boat for sale many years ago and didn't have enough cash to pull the trigger so I turned my friend on to it. He bought it and owned for several years. 3 years ago he passed away and his son sold the Fountain it to help cover costs. Earlier this year I saw the boat come up for sale and luckily was in a position to buy it this time. Feel like I got a bit of my lost friend back with it.

Anyhow the boat hadn't been run in 3 years and is pretty filthy. I went through and rebuilt the carbs, water pumps and changed the oil. I pulled the distributors and spun the oil pumps to get the new oil circulated. Fresh tune up and and batteries and the engines lit off like they were new. I live in the NorCal area and we had a small poker run through the delta two weeks ago. Took the boat and she ran well but feels grossly under propped. 24p 4 blade Mach1 props and I can hit 6k rpm without issue and have plenty of throttle left. I think somewhere along the way someone swapped props. I keep thinking I remember the boat having 4 blade 27s on it. Any help on a good place to start for bigger wheels would be helpful.

Here are the limited specs I have for the engines, I wish I knew more about the motors but I this is all I have at the moment.

BBC It has gold Griffin Marine tags of the valve covers.
B&M 250 Blowers
Dominator 1050cfm carbs
MSD marine boxes
Very short Bravo 1s (they hardly stick below the bottom)

Boat hits 70mph effortlessly.

Thank you

Pics to come.

Congrats. Yes you sound under propped. Friend of mine has 42 with blown 454s and he's swinging 26-28s. My single step 35 with mag motors swings hydro 27s. I'd say you need 27-28s.

Cool read. Great job on getting the boat back in your family.

I was thinking 27-8's as well. I was leaning towards the 27's. Better to error on the conservative side as opposed to not being able to get out of the hole. I appreciate the input

Thank you,

I have a pair of 27 Hydro's quad IV's that were labbed by Hydromotive that I am selling. They worked great on my 32.
