intake

OK, this is kind of last minute but here goes. My boat is currently on the hard. The engine intake thru-hull is being replaced (amongst other things!) The one removed had a screen similar to the one here...

Another thread got me thinking about this. My boat has been in the yard for over a month for some mechanical work and bottom painting. When I took it in I did not close the engine sea water intake valve. Should I be concerned when the engine is started after the boat goes back into the water...

Hi, I’m a little embarrassed about procrastinating for so long about this, but I just haven’t been able to figure out a reasonable solution. I have a 1988 38-200. The engine is under the companionway stairs and the water intake through hull for the engine is under the galley sink. The 20...

Hello All, A while back someone here was asking questions about air filters on Universal engines. At the time I figured that whatever Universal thought appropriate to install on my 5432 was fine. Upon inspection, I have reconsidered that position. The factory air intake "horn" is a funny...

thanks for answering the questions about the valves under the sink....someone mentioned that one of the valves could be for the raw water intake.....im new to all of this...why would there be a valve to let water , sea water or other water come into the boat....why would there even be a hole...

I want to do a preventive clean/empty the raw water intake screen/filter on my Universal 5416 motor. I think it just unscrews, then the screen is accessible to clean of any debris, and then reattach. My questions are: 1) If I close the raw water seacock, is there any other source of...

Hi folks, I was wondering, after searching the list for clues, what kind of sea water thru-hulls are mounted on the different Ericsons for engine cooling intake... Do you have a scoop with slits, or a mushroom type, (or a countersunk type)....and....how deep below the waterline, and where...

I have never liked the through hull for water intake in the 35-2, as it is impossible to mount a sea cock on, and would like to seal it off. Would making a T below the water line of the cockpit drain, and running it through a vented loop, be asking for trouble from air bubbles in the system...

My informal assesment is that the stock 5/8" fresh water intake line for the Universal Diesel engine stops working correctly beginning around 6 Knotts. My guess is that at some point, the sea water passing by the throughhull at a 90 degree angle begins to suck water out of the line. At this...
