Hose size question (1" vs. 1.125")

I'm redoing the ballast and I think I'm all set to do Johnson reversibles. I'd like to keep all the hoses 1" b/c that's what the pumps take but the Flow Rite connectors say 1.125". I'm assuming you just heat it, clamp it and go? The BLACK thru hulls also are 1.125 (or .75). Maybe I'm fighting it and should just go 1.125" with reducers at the pump?

My hull is black and so is my rub rail so I think black would look best but if anyone has pictures that say otherwise .. I think the SS ones are sexy!

Also, I will be expanding the stock 3/4" thru hulls for vents and drains - any info about how folks when about that. You can't really just use a larger diameter hole saw if the there is already a hole.

Go with the 1: hose. The flow loss is negligible, but you cannot compress down the 1.125 hose on the 1" pump outlet, yet its easy warm the hose and expand it over the larger fittings.

I wouldnt bother upgrading the size of the vents, .75 is plenty.

For the drains, are you not going to be reversing the impeller pumps? Drain flow right back out the bottom of the boat?

So the Flow Rite quick release connectors are a 1 1/8" barb. They don't sell a 1" barb (that I can find). http://www.wakemakers.com/wakeboard-ballast-fittings

I was going to use check valves so I can drain out the side of the boat so that I could monitor it. But to your point .. I could leave all my existing thru hulls which would be much easier.

The pumps have a 1/2" NPT so even 3/4 would probably be fine....

Yes, technically, the flow right fittings are 1.125 OD hose barb and there is no true 1" that fits the Fly High W743.

I abandoned that method about 3 years ago due to check-valve failure after one to two seasons. Too problematic, so I have gone back to just simply pumping right back out the intake.

The ID of a .5 NPT male x 1.125 HB, if you found one, would have such a small ID.

Takes some heat to get them on (heat gun is required as a hair dryer won't make it pliable enough). It's Crazy they don't make 1" fittings as is a real PITA to make them work. I did the check valves so I could easily see when they were empty instead of guessing using fill and drain through the single through hull. In retrospect, I'm glad I did and hard to hear pumps when they are buried at the back bulkhead. Also bought the crimped and bands to make it clean. Also Duetch connectors to tie into the factory wiring.
