 Topic: Engine Help PleasePosted: April-22-2014 at 11:52pm |
|
I was wondering if anyone might be able to help me. The video below is the engine of our 1978 Ski Tique with a 302 Ford. The bolts on the bottom pulley came loose and ripped the pulley apart. I replaced the pulley, but now the top pulley is making noise. Also, I am not sure the belts are tight enough. Can someone please tell me if this is ok to drive or if something needs replaced?
My father was always the one who could fix the boat, but he passed unexpectedly this year and now I am not sure what to do. Any help is appreciated. Thank you video |

It appears the top pulley is off center, remove the pulley, and check for slop in the bolt holes, then check the pulley surface with a straight edge, also check the water pump flange to see if its bent with the pulley off.

Seems like when you shook the top pulley, there was some play there. I'm wondering if the water pump bearings (which would be the whole water pump for practical purposes or a rebuild) are going?

It looks like the water pump is toast. i'm surprised it isn't leaking water.

Thank you. Stupid question, is the flange the "shaft" that the pulley is on?

Yep. I wouldn't go and order a pump until you've investigated further. The pulley wobbles, but too much relative |

Remove the belt and see if it's the pulley wobbling or the pump shaft itself. if it's the shaft, replace the pump.
It should look something like this:

Exactly, remove the pulley and wiggle the shaft. It would be pretty odd if the pulley was loose enough to wobble like that unless it was just loose bolts. The current pcm replacement pump is bi rotational unlike the original. If you end up needing it give me a call.
Take more videos of the pieces with the belt off then with the pulley off and we can help you along!! Too bad about your dad but I am sure he would be proud of you keeping the old girl running. |

That sheave on the circ pump sure looks like it's not running concentric! If I can see it in the video, it's bad. Why the fancy aluminum sheave on the crank? Is it anodized? If not, it does not have a place in a marine environment.

Corrosion problem Pete? This one on the water pump of the Shamrock was on there even when it was a saltwater boat back in the early 90's. Had planned on leaving it on there,I guess I should look for a steel one?

Went up to the lake today and took the pulley off. The noise is coming from the shaft. Looks like I need a new water pump. I appreciate everyone's assistance. Thank you!!!!!

A 78 Tique has a REVERSE rotation engine it needs a reverse rotation water pump. You may also be able to buy a Bi-rotational water pump.
e-basic power.com has them. |

Hello,
I finally made it back to the lake and pulled the water pump. I can't seem to find an exact match online. I found similar ones, but they all have more holes than the one I have. Can anyone please assist? Here is a picture. Thank you Ryan |

Ryan, are you trying to post from a mobile device? That won't work unfortunately. You have to email it to yourself, gmail etc., then download it to a real desktop. Then you can upload. Also, don't use quick reply, use the Post Reply button which gives you more options.
