get the trunnion mounts you will not regret it When I did my repower I purchased "trunnion" mounts and then welded them to the Cummins "L" bracket mounts so I could bolt them up to the side of the 4BTs. Honestly I did not know (and still do not) if I am using them properly. I left my engine beds fr...

Rawleigh this is the snubber that some Cummins / DODGE guys are using on their 6BTs. Some of them suggest the .008 orifice hole but they also say you can try the ones that have multiple replaceable orifices https://www.mcmaster.com/3820K52/ this one has a few different orifices that you can change t...

According to your post regarding timing you need to play with timing advance for your engine. Sounds like you do not have enough advance. 100% not enough timing will def give you less power. It will not cause it to drop off tho. When weather is better you can just play with the advance and drive the...

scenarioL113

Just for troubleshooting purposes you need To see what your “all in” timing is and what rpm it is when it gets there. This may not be a timing issue but timing being correct is extremely important for Power and fuel economy. Lets say the timing was a bit off but was close, now you add a little weigh...

What was your RPM the last time all was working properly? What RPM should you be getting? Has anything changed since then? Weight wise, Prop wise? Are you getting your speed? knots/mph...did you change the tachometers? or Alternators or something that may be affecting the tach signal Both engines ar...

Yes, that is what I am referring to. They seem to come in different types. Some offer a very small hole to allow pulsations to be dampered and others that have some kind of porous material that acts kind of like a screen/filter (for lack of a better description by me) that produced the same end resu...

Thanks for that Tony, Good information and that is how I would do it as well if I need to.

When we repowered from 454's to Diesel, the struts had enough meat on them to be bored out to 11/2 " and a thin wall cutlass bearing installed. We replaced the bronze shaft logs and glassed them in . My engines beds were still solid so they got cut down and capped in aluminum. We also went with Cap...

scenarioL113

I am thinking that we will need 1-1/2 shafts and see what struts and logs will work or be needed or how to handle that.

What size are the stock shaft logs and what can they handle up to regarding shaft size or angle???

Thx

A few questions on repowers I am looking at getting a 31 to replace my B28 in the near future. I have not found one yet that I am going to buy.

Does anyone use a snubber for a fuel pressure or vacuum gauge in their fuel system? I have cummins 4BTs and installed vacuum gauges on my filter heads which are remote from the engine. Both my engines send pulses of pressure from the lift pumps that cause the gauges to flutter aggressively at idle a...

I have a B28 and had 350 mercuisers before I installed 4BTs. I think it would be easier to just pull the engines. I know it sounds like a lot more work than just pulling the gear but it is not.

I had a friend that had a 26 Bertram Flybridge. I was on it a few times and to be honest I thought it was a great boat. It handled very well in the ocean and it was pretty economical for a twin screw gasser. His had twin mercruiser inline 6 I/O's. I dont recall the severity of the typical snap roll ...

That is the question... Comes down to what is better for the individual. Look the shaft size of the rudder can only handle so much stress so adding to an original rudder (depending how much you add) is probably OK. A brand new fabricated rudder is def (probably) ergonomically better thought out and ...

Aside from TIG welding this is exactly what I plan to do this winter. Drop them and add a bit in front, behind and beneath. I never made the suggestion as Captain Patrick sold his rudders here. But one could bring to a prop shop and ask them to braze a couple strips on. Same material and process th...

About 10 or 12 yrs ago I modified my original B28 rudders. A friend ran aground and bent a rudder shaft and he gave me his old Bronze rudder. I was able to cut strips off of this rudder and add it to my existing rudders. I added about 1-3/4 on the trailing edge and added about the same amount to the...

scenarioL113

If just looking at "basics" it seems you have an "overloaded" condition. When I say overloaded it may not necessarily mean you are overwheight. I am saying the engine is not able to create the power it needs and what is could be causing it. Diesel will smoke when overloaded or if they are mechanical...

I am no authority on the subject but it does resemble a Ray Hunt Design. Modern technology can def get more out of engines than old technology. They look cool and are twin turbos.

How about piling some wood or something else under the pan. (I do not know how much clearance you have) This way maybe you can just actually drop it enough to grab the remainders of the sheared bolts. You could also go to ACE hardware and get some long bolts (like 4 or 6) and place them evenly in pl...

incoming wrote: ↑Oct 19th, '20, 07:37 Tried both of these methods. Not sure if it was because i couldn't get the studs clean enough, or if the surface isn't flat enough, but couldn't get the bolts to adhere. Held them in place for several minutes, but they just fall off.

You could try brake parts cleaner to make clean and dry

scenarioL113

Getting a drill bit started on a snapped bolt is difficult when you have it on the bench. It is extremely more difficult in your situation. They do make deburring carbide bits. There is usually one in the kit that has a very sharp point. This bit can be used in a high-speed drill and can make a grea...

In reality the oil pan probably will need to be dropped. If you have no other way then drop the pan. I know you probably will not be able to remove the pan without lifting the engine but with the pan dropped there "MAY" possibly be enough of the sheared bolts to get vise grip onto and ease them out....
