INSTALLED MY NEW M5 AND CLUTCH IN MY TEAM PRO THIS WEEKEND!!

[Chris Steffens]

Hi everyone I installed my new M5 motor in my Team Pro that I ordered from Bruce at Enforcer this past weekend. I removed the homelite motor that was in the boat then I put wood dowels in the mount holes then glassed over them. I was extremely happy with the fit and finish of the new motor and clutch! I had to play with the mounting setup in the boat I ended up with the motor center of plug hole 11 1/4 inches from wood on transom. Factory is 11 3/4  from wood but thats the best I could get with my stuffing tube and drive cable. I got 10oz of Bonzi break in oil and fired it up on the tap to set the carb up 644 walbro. Ran it for 10 minutes it is awesome sounding idles great. I need the weather to stop blowing so I can get it on the water. My second Enforcer Revenge boat has the BH 231 modified pum in it with the dry pipe I think this M5 is going to kill it. I will post pictures soon.

I hope you had water running through it. I learnt the hard way and I would hate you to do the same.

[Chris Steffens]

Hi Gordon thank you for the tip. I had filled the tank up with Bonzi break in oil. Then put it on my test stand with the water pump primed fired it up and water was spitting out of the pipe right away. The head seemed to heat up a bit but I think that was because the motor is so tight still. The 1.5 low and 1.5 high factory needle settings were out to lunch on the 644 carb ended up getting it to idle real nice then got rid of the bog when open the throttle she spools up nice. I ran it for ten minutes on the stand. Then pumped all the gas out of the tank back into the gallon jug. I hope it is nice tomorrow it is killing me bud I want to go run this boat really bad. LOL!!!! What prop is going to be the best for me for speed? Thanks Gordon I appreciate it.

[Gordon T Haley]

Start with the stock prop. Then switch to a after market prop. I'm having good results with the Grimracer AQUB9787

Thank you for the prop info Gordon. I had the boat out this past weekend for a few minutes. It was running supper good for about 10minutes then it just stopped dead. I retrieved the boat and noticed the water injected header was quite hot and the cooling cap was pretty hot. I let it sit for about ten minutes fired it up on the hose and it idled great. I put it in the water and ran it around for about 3 minutes and it suddenly quit. I went out to rescue it and pulled the hatch and there was a bit of smoke and it felt hot again. I am running Bonzi oil at 5oz to 1 gal of 87 octane plug is grey to tan when I check it after it quits. I dont know what is going on. It runs cool on the test stand with a bucket of water with hose attached to the back end. I wonder if my water pickup is not deep enough on the back of the transom?  Or if it normal for the motor to run hot on break in? I have the lid on the boat. I also wondered if the clutch burns off some crap that may be smokeing a bit. The exhaust gasket looks burnt a bit. I looked in the exhaust port and the piston has no scuffing on it and compression seems pretty good. Thank you

[Gordon T Haley]

Sounds like you are not getting cooling, I would check the hight of the water pickup also check for crimped hose.

[Gordon T Haley]

Oh also I run 8 oz to 1 gal of gas, no other additives, ethanol free gas.

[Chris Steffens]

The pickup on transom seemed high to me so I filed the alum block a bit because it was all the way down so I filed about two 16th off the block then installed tube with alen key seems to be a bit deeper now. I wonder why the homie ran cool with the pickup in that spot i never moved it. I have now!!! I blew on the tube and it is clear right to the header dump line.  I hope it will run cooler now. Thank you for your help Gordon I really appreciate it.

Chris; You may want to richen up the high speed needle a bit. A gray plug electrode sounds too lean to me. Too lean will also make It run hotter. Safer to start out a little rich which can prevent a meltdown!

[Chris Steffens]

Thank you Theodore whats strange is The high needle is almost two turns out from seat so seems rich and has no go when I open it up on the water doesnt sound lean if anything raspy sounding like its really rich but hot to the touch on the head and smoking hot on the header. Idles great on the stand and in the water but one on top of the water it seems to heat up. But remember It is not Idleing to cool down just shuts off in a turn everytime. My fuel cap vent didnt seem to be working the one way valve was sticking shut. I wonder if this was the lean condition running out of gas because The fuel pump couldnt pull fuel. The primer ball was always full after it shut off the carb is a 644.  I have maybe run a total of about half a tank of fuel through the motor since first start. Thank you again.

[Gordon T Haley]

The WT 644 needles settings are as follows low 1 turn +/- 1/4 ,high 1 5/8 turn +/-1/4, clean the fuel vent and see. You have a water pump + clutch , correct? Is it working? Always have a water pump with a clutch.
