so we learn as we go...and we become experts at the stuff we solved, but are newbies when we encounter stuff unseen before.
I had what I was thinking was water in the gas...but since I had hit my SS prop on my 1995 Johnson ocean runner 115 twice in the previous week...I thought... I MIGHT have damaged the gears...and I told myself a few years ago...NO MORE SS PROPS!...but I chewed up all my aluminum props and on went the SS.. and it just stayed because I procrastinated....so now I am here with this miss...tried switch gas tanks..it s worked for a little while then the miss came back...Next time out I put in dry gas!!!...still the miss happened...and the miss was so strong I lunged forward from my standing position a little when it happened... it was like a hit something under water a few times!!! I thought...that has to be a broken gear floating around getting caught now and then inside the LOWER UNIT.... so I eventually got a rebuilt unit and installed it.....we sure enough...the miss came back... and it was as sporatic as usual. now I am thinking, IT MIGHT HAVE been the water or an electrical miss I have never experienced before....soooooooooo
the question is with misses...either the water in the gas or a bad -clogged carb..... or an electrical misfire...or short.... would either one of them cause such a horrendous miss...that it gives the boat a jolt...like it hit something....ie the people standing in the boat fall forward a little....
I went out sat about 2 miles at 3500...smooth as a whistle....just hummed along...sweet... I thought..."its nice to have the rebuilt LU on"... then while putzing around..the miss showed up.. and it missed often up to 2500 rpm/..... it has never shut me off... and the motor starts very easily, even ay 20 degrees!!...
so what shoud I concentrate on...water in the tank? or carb rebuilds< or Electrical checks???
thanks
