35HP OMC Fun

[xanaphyst]

I have about three different ideas on the water pump. I am thinking of adapting the stock yamato shaft to work with the omc pump, or have a new shaft made. It is the way i will feed the pump that i am not sure of. I will likely try some type of low water pickup method. You would think being in houston it would be easy to find a machinist that is interested but they all want to make oilfield parts.

greyduk...thank for the offer. All I need is for the yamato input shaft to be 6" longer and be the diameter of the OMC shaft from the top of the foot upwards. Does that make sense? paying for your service not a problem.

Help needed...yamato drive shaft coupling...102-405-0001..anybody have one for sale?

Who do i contact for a low water pickup nose cone for the yamato foot or do i build that myself? Thanks for any advice.

Contact Tom Cronk for info on Y lower unit water pickup - he modifies a lot for CMH class. As for the drive coupling, contact Ric Montoya - RPM Marine - at 206-283-4773 (believe he has ad on homepage that will also take you to his website)

Ric Montoya is out of stock on the coupling, I waited too long from the time he gave me the quote until I placed the order...my own fault. I'll try to find the contact info for Tom Cronk for the low water pickup...thanks for the help.

OK..back from work now..time to start looking at this again. Need to weld up my short tower. I've played around with the water pump and yamato foot last night to work out some water pump ideas. I can actually just drill a hole in the lower section of the foot for a low water pick up. The problem then would be that the water would mix with the oil in the foot. The line of thought now is to isolate the oil from the incoming water. This looks like an easy job with some high quality epoxy or silicon. The next issue is to feed this water to the pump. I have an idea for that..see picture in next post.

excuse my artistic talent

water pump just fits inside the stock tower. will have to make a spacer between "cavitation plate?" and lower section of tower that is the same size as my spacer which will feed water to the pump..

drill hole here

[xanaphyst]

This area in the foot casting is where the water will come up into the hollow spacer beneath the water pump. It will be a little difficult to get a good seal between the gear oil and incoming water but we will see what happens.

Thank you to all the people that have responded via private message or whatever it is called. I'm still figuring out this web board as I find it confusing.
