Does anyone have an engine synchronizer that they use with their Diesel engines? (IDK if gassers would be the same bc I use magnetic pickup only) I have a twinscan tachometer that has a built in synchronizer but it is getting faded and beat up. I wanted to go with 2 separate 3-3/8" tachometers but w...

I have been having this problem for last 2 weeks. The port engine will have a miss on startup and clear itself after a few seconds or if I increase throttle. I have had 2 diff times the engine would start and then stall and I will have trouble starting it and will fire right up after a bleed one of ...

Awesome job to your crew! BTW I looked at your classified and there is no logical reason why you cant sell that boat. Looks like it has about $100K in upgrades (half that just in the iron). If I was in the market I would come take a look. That is a fishing machine and prob not a bad cruiser either. ...

Tony, I did install a brand new temp sender last month. I am not 100% sure but will use a laser thermometer next trip out and check diff areas on the block and confirm the sender as well.
I will try to check exhaust water temperature. Thanks

You need to confirm that you are getting proper advance on those distributors. Put a timing light and check.

Do not do anything else until you confirm this.

scenarioL113

Just to resurrect an old thread because sometime when we search old posts it is good to know what the disposition of a situation was. I ended up installing a new block, new head, new connecting rods, new pistons, new cam, new tappets. I was able to re use the crankshaft bc it was in perfect shape an...

If you want CR and V-Drives you can go with the ZF trans. They take standard rotation as the input and then can be shifted for either direction for your forward propeller. I did not use V drives but I did use ZF 45a's on my twin 4BT cummins to give me counter rotation on my inboards. Good luck Frank

Looks pretty cool. Kind of resembles some lines of a B28 but has a windshield of a 31. The hatch covers are B31like as well (even though they lift as a unit). JMO

I am using a new block for this project. I located one from a supplier. I am keeping my original block though bc the cummins dealer by me can repair with a sleeve possibly. I will shelf it for future possible use. I got a new head, block, rods, pistons, and cam. Using my original crank unless it mag...

The damage is beyond boring unfortunately....

After some research I realize that my CPL calls for 16.5:1 piston which are part # 3907156. Seems the B-series comes in a few varieties regarding compression ratio. 17.5:1 + 16.5:1. Seems 17.5:1 is the common one and what I need is not as common. I may have to get a bare block and piece mail the par...

scenarioL113

Thanks, I am trying to research as much as I can. I do think that like you said, the head, block, crank etc are the same. I think it nds to be a turbo long block or otherwise piston compression ratio is different but I am not sure yet. I think the differences are in the injectors and IP and IP timin...

Hi guys, Been off the grid for a while. Just got the bad news from the machine shop. The block is shot, the head is shot as well. 2 pistons are bad and 1 connecting rod is bad as well. The cam looks like 2 lobes are worn too. Crankshaft looked good but didnt magnaflux it yet. Kind of in a holding pa...

The injector issue was prone to the 250HP aftercooled version of this engine. Mine is the 150hp version with no aftercooler and is "supposed" to be bulletproof.

Its all apart now and will update as I find out more.

scenarioL113

I have the engine entirely apart. PITA but we gotta do what we gotta do. I brought the head to the machine shop and they are gonna go thru it. At a quick glance he said it did not look to be from anything I did adjustment wise. He said when he pulls the valves out it should tell him more. I would ju...

scenarioL113

Here is the deal! Not too great. There is mild scoring on the cylinder wall in 2 places. The cumbustion area on the head is beat up, will need to have machine shop look at it to see if it can be used. Piston is obviously garbage. I think both the block and the head will need to be inspected at the m...

The boat is my yard at home next to my pool and pavers so no heavy equipment can get in close enough. (only to the front of the boat). I thought about a crane to rent but by the time I add up the costs doing it this was is only about $400. If I was renting something I would have to rent again to put...

Ok well here is little progress. I have been busy the last month but have been chipping away at preparing to haul the engine. I had to suck it up and buy a 16' I-Beam (6"). I have a trolley and chain hoist already and bought some 6x6's and put this together. I welded up some angle brackets that will...

scenarioL113

I spent a little more time looking over this problem and did another inspection and compression test. The rockers, valves, and valve stems are operating smooth and appear to be working properly. Neither appear to be bent but I did not pull the head. The push rods are also working properly and smooth...

I think it depends on what size they are to begin with. I am not sure if this is always the case or not but will tell you what I think. If I recall correctly sometimes shaft logs and struts are good for 2 sizes, in other words whatever size that is in there now and one size smaller "OR" one size big...

***UPDATE*** cylinder #4 ZERO Compression Looks like the season is over for me. Piston is probably garbage. Could also be a valve but just wont know for sure until I pull the motor. Obviously I will pull the head for starters but either way I am changing that piston even if its not the piston. My gu...

Moeller makes polyethylene tanks. I have one and am happy with it.

I went in with a borescope and dont really like what I see. The piston top is a bit beat up. I am gonna do a compression test but just didnt have time. The broken injector was not showing any signs of melting at all though. I think the piston is showing some signs that it was def getting too hot, I ...

Thanks Pete. Def an injector, they are at the shop now. Just hope no other damage. I had some priming issues with a fuel system leak that I had a hard time tracking down earlier in the season. Needless to say I bled the injector line on the motor probably a dozen times before I found the air leak on...

Thanks to all for great advice and opinion. I owned my B28 since 2000 and I set this boat up with the Diesel repower in 2009 and after 2011 she has sat in dry dock.

Frank: I think you said 17 knots on the second video. What do you typically get for cruise at typical cruise and WOT - also ,what is the fuel burn. Thanks!

Thanks for the input. I really do appreciate it. I am not sold on the tuna door, swim platform, or the large pulpit. It is a beautiful boat but I realistically need to see a few in person close up.

I dont know why it happened. Possibly the bolts loosened up? The coupler bolts are fine threaded and specific for this purpose. Should have lockwashers as well. Not sure if hardened like grade 8.

This is def a process of elimination. I had a buddy with a B26 that had twin mercruiser inline 6's and he had an engine get the oil contaminated with water like you have.

Obviously he was "reaching" too far. IMHO he should have been much closer to the garage which would have allowed the boom to be at more steep angle.

Further more, if your batteries are that drained by time you get back then I would have to agree that the alternator is not charging properly.

A bad ground could cause that but I suspect the alternator.

scenarioL113

Alternator is possible. If it is not charging properly or working properly but intermittently than that can cause issues with your gauge readings. This alternator is doing the house battery as well and can be compunding your problem. I assume your wiring is OK so I would possibly switch alternators ...

I was going to suggest inspecting the oil spring/plunger unit that is in the oil cooler housing. Bruce mentioned that in his last post, I had a similar issue with one of my 4BT's with low oil pressure @ idle. My gut tells me that your alarm and gauge senders are correct. Make sure your idle is set c...

At first I tried a pressure treated 4x4 across the top and a floor jack as my lifting ram and it broke the 4x4 in half.

Be careful, there is a lot of pressure torque building up when using hyrdaulic jacks or hoists with mechanical advantage.

I did this on my B28 about a year ago and I could not get it out in one piece. I had the gantry setup over top and a 2 ton hoist and tried with strapping and it would not budge. I guess it might have gone if I persisted but didnt like the amount of pressure I was exerting so I decided to just cut it...
