Whew !!!!! thanks.
I have a 14’ 1.75” shaft and a rudder that would work with a few modifications if your interested.
Thanks Tuna, I will keep that in mind for later. I haven't torn the boat down yet so have no clue what I need for a rudder or shaft yet. Luckily Door #3 has the same boat and will let me measure up all of the missing running gear.
Since that stuff is already missing, I would seriously think about pushing the prop back.
Story goes when the 35 was made they basically took a 31 and raised the sheer and added 4 feet to the back, prop and aperture stayed in the same location. That is how the JC got the "Jesus Christ!" moniker. Following sea issues.
You can see the 31 in the hull of the 35.
Would he have to change the shaft angle to fit the prop under the shoe? I know the aft part of my keel is very square, so moving it back would provide the opportunity to feather it out like a Wesmac .
Really depends on how far back you wanna push the prop to be honest 2-3 inches would probably be more then enough. But without reshaping the keel by the shaft tube to increase water flow like Larry did on his 31 JC. I think you are trying to re create the wheel. I swung a 23' wheel, go back 2-3 more inches and 24 would fit no problem
I'm not sure the sheer was raised but the 4 ft add-on without moving the prop is definitely true. I would maintain the shaft angle and make a new shoe. Reshape the keel to the depth/height needed. Capt Larry always said run the biggest wheel you can on a JC since the keel is so wide. I run a 23x21 on my 31 with some cup. The other benefit would be a bigger rudder. I've never seen anyone do this with a 35 but it makes sense.
It's deceptive because the rudder isn't present. I believe it to be not that different from my novi.
You can see it in the flare of the bow. The extra 6-8” where the flare changes.
Anyone have a similar picture of a 31 for comparison?
best i got
35 vs. 31
Appears to be true. First time I've seen that.
If the OP if interested in doing the extension I'll take pictures and provide dimensions off my 2001 31.
I am interested in doing some sort of modification. From everything I have read while searching the forums, it seems like I should reshape the keel a bit (to mimic the design of a wesmac/lowell), extend the shaft 2-4 inches to accommodate a larger prop (23-24' diameter), and also move the rudder towards the stern while making it a bit larger. All of these modifications should give the boat a better ride in a following sea and make it handle a bit better in tight spaces.
-On a side note, I am going to add a bow thruster to the boat, I mostly boat out of the Merrimack river in Newburyport so I need the most maneuverability that I can get.
Reshaping the keel by the prop I am in favor of, as far as moving the rudder, I might think twice about it. My 35 was very maneuverable With just the rudder and a bump on the shifter/ a little throttle. I never went bow thruster 2 reasons. Another hole in the boat and 2nd I couldn't warrant spending thousands on something i would only use for about 5-10 minutes a year
Thank you for the advice. What is everyone's opinion on an engine choice if my 3208 isn't salvageable? Vovlo, Cummins, Yanmar, Cat? What is going to be the most economical around 16-18 knot cruise? Also what would give me the most engine room space? I know the CAT takes up quite a bit of space.
Everyone will have a different opinion on that, but it's hard to beat the Cummins Recon program for the cost involved.

...........but if you're in a hurry........just call Gurry
Congratulations on your new project I’m glad to see someone grab the hull and finally put her back to life always said dam shame when I drove buy it can’t wait to see the outcome
