Changed 6bta Long Blocks- Now What?

[JC]

Hello Guys. I have a question for you. We have had a Bertram 31 ("White Marlin") in El Salvador for a little over 10 years. Last year we decided to swap the Cummins 6bta 250hp engines. After a bit of research we decided not to upgrade to higher HP (Yanmars or C Series Cummins) but kept the 250 6bt's.

We thought we would save money by getting just the long blocks and just using all the old peripherals but looking behind we should have just purchased new engines with all peripherals.

The engines have about 200 hours on them now but we have decided that we will start changing all the peripherals (we already changed the injection pumps). We will purchase new turbos and now the question I have for you is it better to purchase brand new twin Disc 502 transmissions or should we just buy the rebuild kits and have them overhauled?

Thanks for your input...

Not sure if they ship outside the US but you could try Mack Boring. If they can not help you out they can probably send you to someone who can.

JC,
I can’t help you with any info on the marine gear, but just wanted to chime in and say it’s good to hear info on the White Marlin.
You guys bought that boat local to me in Louisiana and I know the 2 previous owners..... I also have a painting of that boat at my fishing camp, painted by local artist Fred Marks. Good luck on your upgrades and always great to hear about learning experiences from others.

JC I checked with the vendor I purchased my ZF transmission from locally and he doesn’t rep twin disk. Did some looking and the Houston twin disk rep is Sewart Supply.

I don’t know anything at all about them, but I figured it couldn’t hurt to have another vendor to contact. Good luck.

I appreciate all your help. I finally decided to get the overhaul kits for both transmissions including the clutch plates , seals and bearings. The transmissions have actually been great just one starting to loose oil thru seal (coupling) and I feel they have been thru enough and can fail any day.

Nice to hear some history Ray!! The boat is doing great. Weve been fishing a tournament here for 8 years now got 2 first places on marlin release division, 3rd twice and just finished this past november 3rd in salifish division and 1st in funfish. I love the boat wouldnt consider changing!! I would love to see a picture of the painting please send to jcmarlinsal@gmail.com if you can. I wanted to post an image of how white marlin looks today but cant figure out how to do it. LOL

Thanks all.

Pic a 3rd party host to store pictures...such as PhotoBucket. The free startup works fine.
Sign up for account.

Follow directions on how to upload picture...simple as follow path on your computer to picture you want, click it, accept upload and its on the host si

Then find your picture on the host site, Photobucket its called Library, all your pics display, click that picture and you will get several format options. Choose Share on the right and click, find the one for bulletin boards and forums / img. When you slide your curser over it a link to copy comes up.

Copy the link and past in your response box and your done...at last.


Its cumbersome, but not too bad.

JC,
Just emailed you a picture of the painting. Not the best pic I know.....lighting, reflection etc....may be able to get a better one in daylight. Good luck on your rebuilds.

JC: Change the resolution size of the photo. I had to change to 600X? to get the photo’s to not clip. Set the first number to 600 and the second number will fill in on its own. Most photo websites (Igmur, Photobucket) you can adjust in the photo “edit” part. I was having this happen to me and I changed (edited size) the photos that were oversized in Igmur and it automatically fixed the linked photos at Bertram31. You shouldn’t have to repost them. Boat looks great!!!!
