Yes, Im sorry. I have the twin Mercruiser 350' 260 MIE Engines. I was really anticipated seeing a scaleing issue when I took the end caps off and when I didn't I was wondering if I just wasted money on the new Heat Exchanger. It seem to me that a change in water temperature would not like solve the ...

Morning and I hope everyone had a wonderful Christmas! I've been avoiding replacing the heat exchanger on my 86' B28 knowing ist an expensive item. This past summer I had a slow rising temperature on the port engine at higher speeds that would cool down when I brought the boat back to slow speed or ...

My old girl is running 85' 5.7 Mercruisers 260 MIE. In this video I believe I was running at 3200 RPM's and just under 30 MPH (GPS) engines have approx. 1800 hrs each and they honestly Hummmm at that speed, truly and amazing sound.

This is my 85 BFB after a 120 Mile run from New Port Richey, Fl to St, Petersburg, Fl and back. She is a humming!

It does not appear as thought zincs on the tabs.The holes for the screws are larger then they should be indicating deterioration of the metal tab. Looks like the screws with head still in boat and 3 screws missing. Hose to actuator toren and needing replaced.I dont have a way of lifting the boat so ...

Once again I am looking to the board for some advice. The starboard trim tab came unbolted fro the bottom of my 28FB this past weekend and was hanging by the actuator. I was able to disconnect the tab plate from the actuator and it appears the hydraulic line is also damaged. My question is does anyo...

Thank you Tooez, I look forward to your email with the diagrams. Also, I took your suggestion regarding the ac install and dropped the lower floor of the salon seat to fit mine in that space. It works wonderful. I have a primary 5" duct blowing up from the left locker into the main area but need to ...

Does anyone have a wiring diagram for the 28 Bertram. It would be greatly appreciated.

Took my old girl out today and while just getting up to 3100 RPMs out of my home port, starboard engine shuts down, with no electrical power. After checking for obvious possible signs for the loss of power, I checked the main engine fuse in the vBerth for the starboard engine is was blown. It had a ...

I need some help determining how much fuel I am burning per hour. My understanding is that my B28 with its original 350' gassers burn rate is approx. 1.2 GPH but I was hoping to dial that it more accurately at all RPM's. Is my option to install a Fuel Consumption Guage and if so, has anyone done thi...

Well, it took a little longer to get it to fit than I expected. I had to cut out the bottom of the seat base to drop the unit about an inch. Holes are cut for the 5" duct and electrical going to the units control panel which is installed in the locker. Next will be the seapump to and existing seacoc...

I do have a question about the condensation drain. I see that Toeez mentioned the hose runs through the bulkhead and into in front of starboard engine. Is that where I want it to drain? SHould I be concerned with engine vapors possibly entering the cabin from this location? I'm now to having a boat ...

I just received my Webasto 12,000 BTU a/c from Defender that I am planning to install in my 86 Bertram 28. I searched the forum and was hoping to see if some members had already completed an install like mine that could make suggestions to make my install a little easier. I am considering one of two...

I'm glad you mentioned marine, I would not have thought it made a difference. Ill get some.

Great, Thank you gentlemen for that fast reply. I will go back and add the locking and including antiseize,

Good Morning gents, Yes , this is my first post on the forum. I purchased an 86 B28 FB last year and took it in to the shop to have some work done including tranny seals replaced, When I got the boat back, the coupling bolts were not tightened down all the way which was likely overlooked during rein...
