    getting very hot

    i have a 94 wave raider about one year ago i took the running gear out and installed in my 15ft jon. i love it makes swamp fishing faster. i burnt a piston just before i made the swap. put 82mm in it and has been running fine till yesterday about half way to the hole the mufler started getting super hot. after pulling the ruber hose loose i found there was very little water coming out at idle an no water at top speed. never had this problem before, there is water coming out of weep tube and the motors not running hot. can any one help or have had the same problem thanks

    the hoses for the exhaust or the water jacket around the exhaust might be clogged up with sand or other debris
