    Gasket..Glue or no Glue

    Well, i've decided to try the 2 carbs on my aq120b engine. When I took the old intake manifold off, it was glued to the head. It was a bugger to clean the head, but it's done. Now I need to know if the new gasket actually needs glue. And if it does(and I hope it doesn't) does it go on the head...

    Batteries

    Trying to figure out if I need dual purpose batteries, or just starting batteries. At most while jigging, my fishfinder might be on for an hour or so without the motor running. Then there are the downrigger. They might get used the odd time without the motor running, but for the most part the...

    Aq 120 B temp sensor question.

    I am tryinng to change the temp sensor. Somebody has obviously got there before me. The two part unit that is there is nothing like oem. It has been stripped.

    Volvo 270 Transom plate install

    Im getting ready to put the transom plate back on my boat. Volvo 270. When I removed it, it didnt look like there was much of anything in the way of sealant. Maybe a little of what I think might have been aircraft gasket sealant. But hardly any if that was in fact what I saw. Also there were...

    I have a volvo 280 leg on my boat. When I try to trim it up, the motor hums but the leg does not go up. If you lift up on the leg and give it a helping hand it will go up. When it is up, I can push it back down if I put the weight of my body on it. As I look at the trim motor, I see there is no...
