Hot water on dredge

hi we have an 5inch keene with 2 honda 6.5s we run an heat exchange off 1 of the mufflers attached the problem is we have to have that pump at 100% just to get it hot enough.would love to here of other peoples set ups thanks chris

A 9mm wettie workhorse long john and a 7mm top, socks inside a lose fitting set of boots… the only problem I have is keeping fingers warm

i use about the same set up but after 7 or 8 hours in the river start getting bit cold haha

You need two exchangers 6.5s are a minimum so put 1 on each engine join the 2 so you get twice the heat & twice the flow , youl need to do some research as defiantly want a couple of safety features in there , a mixing chamber is one preferably with some cold water getting fed into it & a reliable disconnect , good inline filters also to stop blockages iv melted hoses off a few times haven’t been burnt but theres a good few guys out there that have so put some thought into it.

Thats an good idea for 1 on each motor and yes ive seen the mixing chambers but defiantly wouldn’t work with the amount of heat i get off 1. and yea i just jam the hose down the zip so if gets hot can rip out quicki have had an close call getting too hot once

Laidlw1… You are a harder man than I… I cannot manage more than 5 hours on a frosty winters morning, on days when I needed to break ice in the pump.

i have not dredged in the winter that would be way to cold.if there ice im not keen haha

Cannot say I make a habit of frosty morning dredging trips… Trick is to put the wet suit on in the warm shower at home… and take it off again in the warm shower at home…

… no, not a week later…

Is this just for warming up the divers?

just od on fluids before getting in ur wetsuit, then as required you can have a little piddle or two when the going gets cold.
