Tony, great reply, gives me more things to look at. I also like your double double filter system since I had them on my previous boat. But at age 85 the agreement with my son-in-law is “I’ll buy the next boat but you have to maintain it”, My mistake was not letting him work with the Racors this time and I think that would have sealed the deal. Still have three Racors left that came with the boat, and will let him do them next time which probably isn’t going to be to far in the future.

So changing to the Double double would be an improvement in that the 19513 would hold more water and the two filters would filter better.Assume it is the —513 that can handle the water. So it would be an improvement to change. Know have to figure out the water.problem. Not sure how water got in unless the filler cap seal is bad. Of course could have come from a bad pump supply as well. The forum doesn’t seem to put much credibility to the idea must keep the tanks full to preclude water buildup; so either it leaked in with the filler cap seal or it was pumped in. Are there other possibilities I am not aware off?? Thanks

[Raymond Slingerland]

Do appreciate the forum. Update. Taking the boat over to the marina the oil pressure settled down at max of 75psi and 35 idle, and although one turbo didn’t turn up during the trip, it did later after changing the fuel filter. It is apparent we need to exercise the boat more frequently. Turn up at dock doesn’t do it. Our bad.
With those lessons behind us I have just ordered your SMX 1730 sea water pumps and going to replace existing ones even though the sales ad for the boat said “new pumps”. The picture seems to belie that assertion.. Kevin in your parts did a good job, Since the 300 hp wasn’t listed in your sales ad I give him a call and after I sent him a picture he said they would fit.Also going to put on the new air filters I got from you as well.
So appreciate all your tips–I’m and old guy, 85, so appreciate putting up with me.

Sorry I am wasting your time. Appreciate your opinion, but answer to question would be helpful regarding oil pump. Help me know how to respond to Mech.
As to function and process for fix. Also, “not one hook up is proper”. Does that mean those shown on the engine are incorrect? Is the pressure line to the gage from the oil pump housing wrong? As noted, there will be a gage and it will be hooked up by a mech. that knows a lot more about it then me. Not sure about the “spend $150.00 and get a gage when it was noted that was going to be done. But it would be helpful if I knew the next step when the $150.00 gage shows high oil pressure so i know how to respond to the Mech’s call what ever it is. But sorry trying to find that information was wasting your time. Rest assured I won’t waste any more of your time after this post. Ray

Talked with mech where we will be pulling the boat Wed. He is going to meet us tomorrow when we bring it in. He suggested oil pump not bypassing as rpm comes up and pressure builds up. Have to lift the engine to remove oil pan to get to the pump. ??? Mech. will have a pressure gage to hook up first. Will he hook up at the top of the oil filter housing where the source to the gauge on the instrument panel originates? And do you have to remove oil pan to get to the pump?

[Raymond Slingerland]

Will have gage hooked up tue. afternoon and go on the hill Wed morning. If pressure is high what is the next step?

[Raymond Slingerland]

Ok, will do. If pressure reads high as before what is the next step?? Thanks

[Raymond Slingerland]

Ok, got some help. Pressure comes off of the top of the oil filter housing in a large hose. Od looks to be at least a 1/2 inch. Than in the bulkhead up to the gage it narrows down to the very small house as picture. Even though I changed the oil filter, would remaining residue else where in the system cause the oil pressure to be high coming out of the top of the oil filter housing?

[Raymond Slingerland]

Than would pic. 2 represent the oil pressure to the gage?
Also, are there some sources here on the forum that would show the type, location, etc. of the zincs on the engine?

[Raymond Slingerland]

Here are pictures and numbers.

Picture and numbers. Appears to be two hoses off top of block, forward on the engine. The smaller hose seems to match the hose on the gage.

They are what I ordered. Should get them Thursday. Thanks.

[Raymond Slingerland]

Good to know that it is serviceable. Thanks

[Raymond Slingerland]

Here are a couple from the survey. I admit I don’t know what the aftercooler looks like on the Cummins. The drawing posted earlier didn’t print out for me.
These are jpg so not the best but??? If they aren’t the serviceable after coolers than the owner’s mechanic is misleading us, since he indicates he has serviced them in the past and told us how to do it—but maybe that was all on an engine that could be serviced. If they haven’t been upgraded give me a ball park dollar number to do that? Thanks

[Raymond Slingerland]

Can you tell from this picture if after cooler has been upgraded?

[Raymond Slingerland]

CPL 0970, SN 44547345.
Understand they are early 90s engines. Some had non serviceable after coolers I am told. But since the mechanic indicated he had service them before I assume either these have been changed or were not the non servicable ones.

[Raymond Slingerland]

Great article that was referenced. Owner is going to have his mechanic check it out. His mechanic thinks it is dirty aftercooler since he has worked the boat before and knows the existing configuration can do better.

Reference the props–Since props move the boat I would like to have the best prop fit, and I understand the biggest diameter should come first and than pitch to make the desired rpms. If that is correct, the tips on the existing 3 bladed props on the boat are at least 4 inches from the hull. It is my understanding that could probably go up to within two inches of the hull. At haulout could not see any numbers on the props, so probably covered by the nut on the end. Owner doesn’t know prop size or pitch, just that they have worked for years.

[Raymond Slingerland]

Very little, some what grey. Not steam.

[Raymond Slingerland]

Bill, your reply is most appreciated. You have hours on those engines which give me some good confidence that they are worth considering. I will continue to consider them. As a matter of fact the Bertram, with the lower helm is an example of the boat that might work for me, but if flybridge has to have the lower helm. Want to cruise 20 knots, in air conditioned comfort, and have to travel 50 miles to the fishing grounds. Would prefer 31 to 34 foot boat, since I have large family but the Bertrams that size wouldn’t make it with just the 240s, so it is a trade off. Know the Bertram is deep V and heavy but some of the other 31-34 boats might make it with the 240s. Thanks for your post.

[Raymond Slingerland]

I understand hp, versus, size etc., for a given performance so that is a consideration. I also understand use and care is a big factor. However if the boat has the 6 LPA engines than I have to determine if valve seal was an issue and if so was it fixed. Also reading the forums regarding the 6 engine hasn’t been encouraging. Is the 240 history any better or should I give up on Yanmar and stay with Cummins. I am unable to do the very through detail investigation needed to fulfill your approach, when boat is 1000 miles away. To some extent I have to roll the dice. Now, IN GENERAL, my understanding is that my odds are better with a Cummins than a Yanmar. Parts are cheaper and more mechanics can work on them. And in a heavy duty use they hold up better. So, if I roll the dice is the 240 a better risk than a 6LPA? Thanks

[Raymond Slingerland]

3 or 4 inches difference shouldn’t be any problem in the Stamas 32 as I recall from crawling around in the engine room with the 454s. But I have to see pictures of the 6lp to see if the additional 3 to 4 inches for the Cummins would be a problem. Thanks for the drawings. A little easier to see than mine and I didn’t have a tx. on the Cummins. Also the height was another consideration.
