Chris Interesting. Thoughts on tabs on a 31 are mixed. Most find that they help in a head sea. What did you find out about Zip Works? I believe they were originally a Volvo product. The attractive thing about them is that they won't get in the way when you are fishing. Just not sure how well they w...

Thought I would share my experience with adding trim tabs to my 31 Bahia. My 31 is on the slower side, running twin Perkins T6.354 at 185hp each, with Hurth 2.0:1 transmissions, 18x23 Nibral props with a 060 cup and 1 3/8” shafts. After taking with Bennett, Lenco and ZipWake I decided to go with Ben...

Just renewed my insurance on my 1970 Bahia. It was with Markle.

If I could add my two cents from my own experience. Had the same issue on my old 28. Accelerating around 2400 rpms the starboard would would do the same as yours. Went through all the fuel and ignition systems. Came to find out that a wire on the back of my start/ignition switch was broken. Fixed th...

I did a little experiment. One year I did the Home Depot cold galv spray on the shafts and props. I put 100 hours on the boat that season and when I hauled out there where barnacles and growth all over them. Last year I cleaned up the shafts and props and used nothing. Put 93 hours on her and the ru...

Does anyone know if they make inserts for the rear deck hatches? Would be nice to have some extra storage or even to put fish in. Thanks

Just though I’d share this. We have gone to the last 4 and have had a lot of fun. Hope to see you there. We are pleased to announce the 2021 Northern New England Bertram Rendezvous will be held at Provincetown Marina this year July 16 – 18! The marina would prefer that you call and book directly wit...

Thanks Yannis, I would've have really liked to make the deal happen and still would be interested. Perhaps the broker could do some more research on the US boat buying process and see that there is nothing wrong or concerning with doing a deal this way. It would be really cool seeing my old boat cru...

Thanks Pete, I feel I’m in a pretty good spot. If it sells we are getting another Bertram. If it doesn’t I have a great boat to use.

That is my boat. The buyer was from Greece and doesn’t understand how a boat mortgage works. There is no financial burden on my boat. And your “friend” dicked me around for 3 months and backed out on acceptance day.

Thanks Carl. Like I said I just like learn everything I can.

Hey all, I was just curious on what the deal is with turbo blankets and exhaust wraps. I don't have them on my engines and doubt I even need them, but I like to learn as much as I can about marine diesels. Thanks

Thanks guys. I appreciate the info.

Hey all, Happy New Year. I’m starting a list of projects that I need to do and parts to order for the boat and was wondering if anyone can help with sizes. I need to repack the rudders and shafts this season. What size packing and material do I need. The rudders are stock 31. The shafts are 1 3/8”. ...

I’m in Boston at the Old Colony Yacht Club. Just hauled for the season also and looking projects I might want to do.

Hey guys, thanks so much for the info you have provided as I continue to upgrade my boat. I am going to be installing a Bennett tab system. Going to go with 30x12’s. I was wondering how far up from the bottom of the V did those with tabs measure? Should I go with Bennett’s recommendation of 8” from ...

Just wanted to say thank you for all your hard work keeping the website up and running. Great work on the switch over.

Hey guys, I’ve red quite a few posts on trim tabs on the 31. From what gather they may be beneficial to slow speed cruising? My 1970 Bahi Mar has low horsepower engines (Perkins 185hp) I cruise at 16kts fully loaded. I’ve been running the boat with no tabs for the last 3 seasons and never had a need...

My 1970 Bahia Mar is for sale. Diesel powered. Smith Yacht Sales in Hingham, Ma has the listing. Boat name is Mercury. Let me know if I can answer any question for you.

I have a 1970 Bahia Mar and the visibility is great for me. From the helm I can see 360 degrees with no issues. I stand an even 6’ if that helps your question. Good luck with the boat.

Thanks guys for the info. Looks like I got it now.

the number is on the transom in the bilge area

Does anyone know how to decode/read the hull number? my boat is a 1970 31 Bahia Mar and the numbers I found on my hull are 31-6964. thanks

So i've read a bunch of posts about trim tabs and our 31's do not really need them. What about for a 31 that has a slow cruise speed? My 31 Bahia has twin Perkins diesels at 185hp each and that gets me a cruise of 15-16kts. No speed demon but she sips fuel. Do you think with a slower speed like I ha...

I was there. I had a great time. Met some new Bertram friends and hung with some old ones.

We will be there.

We will be there. Coming in Saturday leaving Monday. We only had 3 boats last year so I'm really looking forward to seeing more Bertram's. Everyone have a safe trip and see you all Saturday.

Hey there, just reading this now and not sure if you got your problem figured out yet. I just had the same issue and it ended up being a bad ignition switch. On the back of the switch one of the posts were broken. Replaced switch and all was good.

I am currently running 3 blade bronze 18x22.5. Engines run up to 2800. I have been trying to find what the max rpm is for these engines but can't seem to. 2800 may very well be the max rpm, I just want to make sure.

Hi all, I just got a new to me 31 Bahia Mar. Engines are twin Perkins T6-354s with Hurth 2.0:1 transmissions and 1 38" shafts. Current props are 18x22.5 with .060 cup. I am getting my max rpms (2800) with a top speed of 20-21kts. Cruise is 2500-2600rpm at about 15-17kts. Trying to find out if I can ...

Hey all, I have a 1977 B28 with Mercruiser 260hp motors and a hard top. My current prop size is 17x16 and the boat runs with in the engine specs. I run my boat at 2800-3000rpms and very rarely above 3000rpms. My cruise with full fuel and gear is around 18kts. I was throwing the idea around to have m...

Has anyone installed cockpit controls on their B28 flybridge? I'm tossing the idea around as I like to be able to jig and troll while fishing. Thanks
