You guys not using braided line are you just using regular automotive grade heater hose? I was thinking of using some of that clear braided vynle hose crime Hd, thought it would be pretty cool. Be able to turn around and see the warred flowing also be able to see if any crap is in there.

just remember that if you're not using a pressure regulator... the pressure in those hoses can get quite high. also keep in mind that the hose might look cool on your first trip out, but 16 hours of sitting out in the sun could bake it and make it brittle... then you toss the boat in the water and poof you have a big big leak.
use what doesnt leak and lasts. spend your money on good hoseclamps and not vatozone china junk.

I'd go with regular heater hose and like mentioned above, some good clamps
-
auto cooling sys run at what 16psi or so are jets run wayyyy more than that. i know i know every joe shmoe runs heater hose for the last 30 years and has had no problems.... well im not joe shmoe and not even close to that lucky... so do yourself a favor and at least get the 300psi hose and push lock a/n fittings and never worry about blowing a hose and sinking your boat with your family....

x2 do it right the first time

I did push lock earls and covered the red part with heat shrink to match the plug wires...

Not saying heater hose is best way to go but if you are running enough pressure to blow the hoses you are probably going to have issues with intake gaskets too. Just sayin.......

rather have a problem with my intake gaskets than cooling lines, one will sink you while the is just an oil change :-\

I agree with Ralph , last thing you wanna do is take on water !
-
Why are you okay with blowing intake gaskets? Do it right and do it once. When you're boating your shouldn't be worried about blowing motors up because of water pressure and possibly sinking your hard work. Take your time and save yourself money in the long run. You still have time before boating season.

And Ralph has a valid point. Personally, I've run both braided and regular heater hose. My preference is to run the Blue Goodyear stuff (I've used up my supply of "Rainbow Brite" band-aids messing with braided SS...... THAT stuff is brutal to work with......and totally unnecessary save for the "Bling" value....), but I've also run regular NAPA 5/8" hose, hose clamps, with zero problems, save for one incident at Lake Mead where a hose blew off because some idiot (ME, although I still blame RJ for that just for convenience....) forgot to tighten ONE hose clamp..... Then again, I've always run a valve at the jet to control water to the engine.
Where pressure from the jet tap used to be a non-issue (Within, say 15-20 PSI, where the old boats of the 70's ran forever as they were) I think that has changed with current equipment, parts available and tolerances. It can be hidden just in changing the impeller and wear ring to a modern one in a pump yourself and the pressure from that tap that goes to the engine can double.
THAT being said, the hoses are not the weak link. Rarely do you see those things fail, even standard cheapo 5/8" heater hose from Pep Boys. What fails are usually head gaskets and intake gaskets that cause the "Milkshake" from this.
Not to counter Ralph, or anyone else, but standard heater hose can take any reasonable pressure your pump can deliver out of that engine tap. The hose will NOT be the problem in an over pressure situation. It'll be something more serious.
