Great video…. Going to do mine soon. No idea of proper torque for bolts? Now I see it looks like the bolts are reverse thread which I wouldn’t have suspected unless the camera is playing some tricks…

I have the same engine in a 93 Formula. Great video btw, I’m currently not getting water flow out the port side “ behind captains chair, I may have my sides mixed up” through hull exhaust. I often wondered how much water falls down into the stock stern exhaust and doesn’t make it through the captions call mechanism? I’m going to dig into this issue but wanted some feedback back on if this is common and where to start looking as far as why I’m not getting good water circulation out the port exhaust? Starboard side looks to have decent water flow out the through hull exhaust. Btw currently not having an over heating issue. Also experiencing some new electric issue that is effecting the firing but thats another topic if anyone is skilled in this area I’m all ears. Thanks

Thanks for the video! I noticed a small leak around the gasket of the risers on my 1996 aquaton 2350(kind of rare boat) with 350 Mag when i ran it on the hose to get it ready for summer. I have pretty much the same set up but i have hoses connecting to my risers where it looks like yours are capped off. I found the the leak was coming from the hose. But since i pulled the riser off the gasket was falling apart anyway so i will replace them. Im in Ohio too. Do you ever take your boat to Alum creek at all?

Glad the video helped out !!! No we don't ever go to Alum Creek. I'm 2 hours away from Columbus right on the Ohio River. We mainly boat there but do like traveling here and there. Maybe one of these days we will. Thanks for watching

I know how to replace them, but just wanted to see if someone else used gasket cement. I can't tell if the old ones had cement on them or not from the last person who changed them. Guess I won't use any. (Note: the first camera was oriented correctly, but the second one was a reversed image) [ I wondered why all the accessories were backwards of my 454, and unscrewing the bolts in a clockwise direction ]

Yes, you are correct on the camera. I didn't realize when I didn't get video that everything would be reversed like that. No I did not use any gasket cement. My originals didn't seem to have any on them. I've ran the boat 3 times now and not a drop of water whatsoever. Thanks for watching 👀
