75' Running on a cat. They cop a fair bit of ingestion especially when its rough. Is the danger of this that when not being used the combustion chambers/crank can corrode ? .. Apart from redesigning my pods and getting xxl legs, so as to raise the motors. There is little I can do.

I run xd100 on tc-w3 setting . Would fogging after each use be any help if the motors are sitting for more than 4 weeks

I think running the winterization procedure would help to give the internals extra oil while sitting up.

Thanks Rick. Yes I have a good 15 mins of "no wake zone" Gladstone marina Qld. I also sit with the motors still running after dropping my deck hand (son) or deck boss as he likes to call himself.š¤£ off at the ramp so he can go retrieve the car and trailer..

Does the ring gear on the flywheel look rusty?

Yes there is. I have seen some snorkeling on several cat hulls. Certainly within my capabilities of doing. Anybody out there undertaken the job or have them on their boat ??

KevNZ . I see in your profile a hobbie/possession/addiction š is boat racing. Do you have snorkel setups on those high output , high performance motors?

Where is most of the salt water spray hitting your upper motor at? front, top, sides or back?

Hi bunkergroup. I have a jackaroo 5.5 angler cat running twin 90's. I put the post up about the rust on the oil pump bodies. What year model are your motors. Have you noticed the same. Have you taken the bottom covers off and looked at the front of the motors. There is an oil line fitting and two engine mount nuts that go a bit rusty as well. I will be doing as suggested here and rinse the motors in fresh water after each trip. As I have not owned the boat long I will be keeping an eye on how much salt appears under the cowl after a trip. I don't think my boats previous owner rinsed the motors and the salt I am seeing is an accumulation over time.

Steelhead. Its more mist than splashing that the motors inhale. There was a deckwash pickup running off center of the tunnel that was splashing the starboard motor. I have moved that.

Mlee76. I'm on my 2nd set of 07 75,s . The 2 I have now were at 60 and 80hrs when I purchased them. They are at 400hrs now.. Yes I have the side covers off regularly and have the bolts you mentioned and lower inlet manifold nuts wrapped in denso tape. Its a constant battle against corrosion.
