Big Boys Toys,
No I have #6 drives my pickups are on the transom on my Nortech Cat. Yet to pull off any coolers hopefully this week I can get to it and let you guys know unless anyone else has a solution |
nsxpert, I'm having the exact same problem with my starboard motor. Have you resolved your problem? What was the problem?
|
Tsunami LC,
I noticed my water pump was leaking thru the wheep hole in the front so I rebuilt the pump hoping it was airating and overheating. Took her out this weekend and it ran fin never really pushed it past 110 but still noticed the temp was like 5-8 degrees warmer. Not 100% sure it it solved my problem. Hoping I can figure it out before the Keywest poker run in a few weeks. If you find anything else as the culpret with yours let me know. |
nsxpert,
I have my boat out for the winter with other projects (paint, drives, etc), but I will let you know what if anything I find when I run it again in the spring. Thanks and good luck in Key West |

I just replaced all 3 impellers in the raw water pump and im getting great water pressure but it still gets hot when running hard. I'm guesssing I probably have some seaweed or sand that passed through the strainers. Anyone experienced this and had good results?
Maybe backflushing the system? Possibly inside the oil cooler? What would be the easiest way to backflush the system where to start and finish? Or any other suggestions. Many times when we see a part throttle over heating issue it ends up being a lean spot in the throttle posistion. That can account for highway overheating at a set RPM like 3500 where it doesnt over heat if it stays under 3000 etc. Do you have O2 sensors of anykind on it? |

If your engines were working fine before you changed the water pump impellers, then you may have torn and broke off your new ones. Sometimes it takes a while to prime your water pump after new impellers are installed. If this is not done correctly, you can destory your new impellers. After you changed your impellers, did you start your engines in the water for the first time or on the trailer with a water hose. Hopefully you have a seperate water hose connection on your boat and you do not have to rely on those water clamps that attach to your stern drive. If you started up your motor in the water for the first time and left it at idle, you may not had enough RPM to prime your water pump. Result is broken impeller blades.
anyone else do that? |

Just a tip I always pack my impellers with vasaline or something that will lubricate them for a few minutes while they prime it will also creat more suction with the better seal which can help prime them better in the first place.
anyone else do that? I use non petroleum lube found at most pool stores for pool orings http://www.intheswim.com/Pool-Equipm...mula-327-Lube/ |
