The iboats forum moderators are excited to announce that at this time it appears the iboats forums posting pictures function is working once again. Though we cannot promise for how long, we're hoping for indefinitely.
I need to change the u-joints on my Mercruiser Alpha One.
I have the outer yoke off, and the center socket ring, leaving only the inner u-joint in place at the lower unit. The end caps of the j-joint next to the lower unit won't come off because the retaining nut driveshaft housing is in the...
I had the coupler go bad on our 86 SeaRay Mercruiser (Alpha 1).
I pulled the motor and changed the coupler, no problem. I've pulled the Ujoint from the shaft and using the shaft for alignment (yes, the shaft fits correctly in the coupler).
I can get the shaft to go into the coupler, but it's...
We've got a 85 4 cylinder 140 hp 140 Liter Mercruiser that started having an idle problem. Compression check showed 60 lbs on #2 and #3. Removing the head confirmed my suspicions that the head gasket was blown. Further inspection shows a hairline crack between the two cylinders. <br /><br...
Well, we go the 80 150 hp rebuilt but the problem is that it overheats. We are running with the muffs connected to the water intake (and a garden hose).<br /><br />The water port on the bottom side "pee's", but not like it should. We were very careful to make sure that all gaskets were matches...
I noticed in the gasket set that I ordered for rebuilding the 85 Evinrude v6 150hp, that there is a gasket that goes between the two pieces of the heads. Is there a reason to remove the bolts on the the head, and replace the gasket? Is there anything else between these two pieces of the...
I have a couple questions about installing the pistons on a 150p V6 Evinrude. Most of my rebuild background is v8 autos, but I want to make sure that I get this right.<br /><br />1. I need to use some form of grease to make sure that the pins in the wrist pins stay in place while I replace the...
I'm working on this v6 Evinrude block, and had one cylinder bored out (.030) and the other's honed. I'm working on trying to break the edges, to keep the rings from catching. I can use my dremel tool to get at the upper lip, but I'm finding it hard to get at the lower lip of the port. How is...
I've got my 1985 V6 150hp Evinrude block bored out and ready to start re-assembly (all new pistons, 1 at .030 over) and the manual that I have tells me to use a "non-hardening" sealer on the gasket surfaces and the threads of some of the screws.<br /><br />Can someone fill me in on exactly what...
I've got an 1985 Evinrude 150 hp powerhead that had a broken ring in the #1 cylinder, and several others are scored (rings are stuck).<br /><br />Can I replace the 3 bad ones with .030 oversize, or do I need to replace all of them? If I do just replace 3, will I need to rebalance them?<br /><br...
I'm working on rebuilding the powerhead on my brother's 85 Evinrude, 150hp. I've rebuilt a number of auto engines before, so it's not new to me.<br /><br />There are at least 3 cylinders that are bad (broken rings, somewhat scored) and I'll have to have them (probably all) bored out .020 or...
