As most of you know I have tested many different props trying to find the one that will get this Mercury Pro XS turning 5600 to 5800.

When I was recently fishing down at Lake Guntersville, I began seeing some issues that I knew wasn’t right.  At one stop we made when I looked back at the engine I seen fuel skim on the water.  I went back and made sure connection was all good.  Which it was but never seen where it was coming from around the Mercury Pro XS.

I also noticed a slight miss on the engine from time to time that made me wonder if I had a bad plug or something.  The engine would still turn 5300 to 5400 but that was about all it would do and this was with my Tempest Plus 19p prop.

When I returned from Guntersville early April, I decided I would change out the plugs thinking maybe going through engine break in they may have been fouled up.  My engine has about 34 hours of operation on it.  It will be a year old end of June when I picked it up.

When I removed top right plug and looked at it I about died.

As you can see it has seen better days.  By the way these plugs are about $140 for six so I hope they don’t need changed out too often.

Well I knew it was bad, since the entire metal anode and such was not there and it had only one place to go.  I got on phone with my dealer who told me to get it down there so they can take a better look at this.  Once they got it tore down and pictures sent to Mercury.  Mercury arranged for a new powerhead and injectors to be replaced and got them there the next week.  I was out about a couple weeks but due to timing of me getting to my dealer nearly 5 hours from me we needed to work it into my schedule.  Dealer Unlimted Marine offered to provide me a loaner boat while mine was being repaired.

John Stivers & the Unlimited Marine Team took care of everything in quick order and let me say knock on wood it is now running great.

Once I got it back I did have to go through break in period again, I think this had been a issue for some time even while I was going through testing many different props.

I am now running a Tempest Plus 19P turning 5800 easily now.  Have seen 57 mph with just me and with full tournament load myself and co-anger runs about 54.  Have hydralic Jackplate ran up about 2 inches.  Hole shot is super quick and has great bow lift.

May want to play with a 4 blade 19P or a 3 Blade 20P down the road.  But very happy with the performance that I am seeing since this repair is behind us.
