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.
The backyard "supermechanic" *sarcasm* that I bought my 79 Doral off of stored the boat one winter with the motor trimmed up. Well.... you guessed it... a critter chewed through the main Bellow. So he replaced the bellows but evidently didn't have the spreader tool and the ridge inside the...
Changed the water pump impeller on my 79 mercruiser 165 hp with Mercruiser 1 drive. When I put the upper and lowe drive halves back together there was about a 1/16 inch gap between the two pcs. As I was dropping the top down onto the bottom I turned the shaft and felt it drop into place but no...
When my boat started leaking I had to check my bellows. When I pulled the drive off I noticed the u-joint bellow had water in it and the gimbal bearing was rusted. My hinge pin tool finally came in so today I removed the bell housing and bellows. I took special care removing the bellows to...
Hey, was hoping someone here could help me out with a problem I'm having.
First of all, my motor is 1979 Mercruiser 165 hp in-line 6cyl. It has a Mercruiser drive.
1st problem: Is it Mercruiser 1 or MR drive? I'm ASSUMING it's MR due to the year
2nd problem: When ordering a water pump kit...
For the life of me I can't get the search function to work in my favor. My prop has pitting in the blades and calcium spots all over. Also my trim tab anode his pitted all to beat hell on the port side. The trim tab however was turned towards starboard side sightly.
Is this pitting of the prop...
Today I dumped the boat in the water and it is definately leaking through the transom assembly somewhere. A constant trickle at about 1 cup of water every few min. This is with the engine shut off. I looked at the bellows as best I could utilizing a telescopic LED and telescopic dentistry type...
Just curious. My transom plug was leaking via the bolt through the middle. I'd say when I filled up the bilge with water it was dripping a drop about every 3 seconds. Now my question is.... when the boat is in the water is it possible that with the added water pressure a drip like that could let...
Hi. My boat has recently started taking on about 2-3 gallons of water per day. I notice that there are two rubbers between the transom and the outdrive. One large one which I'm guessing is the main seal and another below it which is longer to allow for more movement and is about 3" in diameter...
Tomorrow I plan on installing my second battery and battery isolator along with my 1100 watt stereo to get them musky riled up. I've been looking through the service manual. Am I correct in assuming that the orange wire at the battery is my alternator output wire to charge the battery? (Assuming...
I have a 1979 165 hp Mercruiser in-line 6 cyl motor. Currently there is only 1 battery in the boat. I bought a second deep cycle battery and a 90Amp Battery Isolator. What I WANT to do is run the current electronics and ignition off the battery that is currently in the boat. I have a 1 amp solar...
I've made a couple other posts on my "issues" however as symptoms have become more clear I figured I'd start another post.
1979 Mercruiser 165hp in line 6 cyl.
Initially, the boat seemed to be stalling and not re-starting once it got warm. So this morning I bought a new coil for it. Fired it...
As I'm broken down on the lake and not at home to check service manual, I was hoping someone could tell me what proper resistance should be for the coil on this motor. I don't want to spend money on parts if I don't need them. Also, on a coil that's going bad, will it give a bad resistance...
Let me start by saying I'm not in danger and a nice fellow has offered me his dock and a ride home. But when my 79 165 hp warms up it dies. Not overheating. Got fuel in the lines. When I turn the key its firing briefly. A sputter. So I have spark. But I'd rather not have to come back tomorrow to...
Just picked up my second Doral (First was an 84 14 1/2' runabout). It's old but everything works and I can't wait to get her wet!
18 1/2' w/ 165 hp Mercruiser in-line 6.

Hello, been browsing the forums for a while now and I could really use some advice.
I've just purchased a 1979 18 1/2' Doral with a 165 hp in-line 6 Mercruiser engine. Never before have I owned/maintained an in-board motor.
So if you could humour my ignorance it would be appreciated.
A.) I know...
