2002 Crownline 230 BR with 350 mag Bravo III 0m326575

Boat is new to me, previous owner claims no overheat which I now doubt. I have replaced manifolds and risers as well as new impeller and seawater pump. Runs great on muffs however I shut her down when temps hit 180. I took off t-stat housing and to my surprise - no t-stat. The boat has been only in salt water so I took off the water hose connection on the inside of the transom and the passage is almost completely occluded.

My question: should I try to replace the water hose or just go ahead and do a thru hull conversion? I'm not sure I'll be able to fix the hose to be honest - I could barely get the hose connector plate off the transom and even if I get it off I don't think I could get the hose fitting tool to fit without pulling engine.

If I go with the conversion, can I leave the current set-up and install a T fitting or is the block-off plate the only way to go?

Is there a better option? Is there any downside to a thru hull conversion? Are there advantages to a thru hull?

Thanks, I did read that thread but did not look at the option in post # 20. Seems like a viable option. Know of any one who has used it?

Any thoughts on how to get the OEM hose removed? Even if I remove the power steering I don't have much room. I had to grind down a socket just to get the hose adapter off. I wish I had done this when I had the manifolds and risers off.

Howdy,


I didn't see any mention of ensuring that the raw water supply hose(s) power steering, oil, and/or cool-fuel heat exchanger being completely free of debris or replacement of the T-stat. My oil cooler was COMPLETELY plugged with debris from previous raw water impeller failures!

Do not run without a thermostat....

You DO NOT need a thru-hull raw water source.

The drive raw water pickup provides more than adequate flow to cool your engine. (mine cools my 7.4L engine WITH closed cooling in 85 degree F water)

Also, if the hose from the transom to the raw-pump, is NOT a heavy, stiff OEM hose (someone replaced it?) , it could be collapsing from the suction produced by the raw pump.

I would replace the partially plugged hoses, and ensure all the other rawwater hoses and coolers are clear and continue to use the drive pickup. Just make checking them every few years part of your maintenance. If you ever replace the engine, consider adding closed cooling.



Regards,



Rick

Appreciate the input. The t-stat and the water hose were my first "finds". I will not run without th thermostat. Fortunately the impeller was not in pieces, just worn and the housing had some scores so I opted to replace. I will flush all the other potential blockages. The hoses are all OEM and in good shape.

My concern is more about how the heck I'm going to get the new hose on. I don't see how I will be able to fit the tool and the tapered fitting in the space, even with removing the power steering

I would suggest that you don't just "back-flush" the system but actually remove components and visually inspect.

It might be previous impeller failure(s) that has resulted in debris in either hoses or the PS/oil heat exchanger. (you may not have an oil cooler)

If you're talking about how to get the new hose on the transom fitting, you might just replace it. If you cannot get it on the pump housing, (this is a new housing?) you might have to heat the hose a little with a heat gun to soften the hose.

Which "tool" and "tapered fitting" are you talking about?

Timely post - I have a 2003 CL 230BR, and was considering tackeling the outdrive service myself. My plan is to replace the bellows / water hose / drive oil hose / senders. I'm reasonably comfortable with the steps involved, but I've been scouring the various forums before I dig into it looking for where others have had issues. The outdive oil line fitting breaking off is one area I want to be careful of. The second "problem child" seems to be getting the tapered insert into the outdrive water inlet hose on the transom side. I'm pretty sure this is what you're talking about. Just not much room to work in there.

As you and I have the same boat, I'm going to be very curious to see how you end up dealing with this. Pics would be great. Keep the posts coming!
