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.
hey all, Just after a bit of advice if anyone can help. <br />I have a merc 650 and the steering has gone tight. I have disconnected the steering cable and it is the vertical pivot tube at the motor sideof things that is stiff. I have re-greased it, pumping lots of marine grease through...
I have a Fuso 320 sounder in my boat at the moment and recently found on the bank of the river a transducer from a Hummingbird that had presumably been broken off a boat and drifted ashore. At present im also looking getting a little car topper dingy and was wondering if I can connect the...
Hi there guys, hope you all had a great Xmas.<br /><br />Sorry in advance for the long post, but I think i have to explain the background to this problem first.... ;) <br /><br />I have a 71 4cyl merc650 which has good compression (~130 on each pot). A while back, my distributor packed it in so...
hi there folks! <br />I have a question regarding my 71 merc 650 - 4cyl. My latest battle has been with the distributor. Unfortunately the 3 low-tension wires leading to the dist housing corroded away. Ive come up with a 2nd hand distributor (new ones cost $512 here), but its off something...
hi there, Just wondering what will be included in a carby rebuild kit? (1971 4cyl merc 650 65hp)<br /><br />I had a look at<br /> http://www.mercruiserparts.com/Show_Pictures3.asp?dnbr=%2056973&ivar=images/MERMAR/56973/14.png&inbr=450&bnbr=9&bdesc=CARBURETOR+ASSEMBLY <br /><br />and noticed...
Here's a question that will probably stir up a bees nest.<br /><br />Background: have a very old merc (1971) engine that has got the odd problem with it. Current repairs will cost me about $700 in parts to solve the problems that i know of at the moment... (in fact theres a rattle i know of but...
Hi there - i was hoping to get some help with the timing adjustment on a 1971 merc 650 4cyl that i have. (serial # 3157960).<br /><br />Im looking at adjusting the timing and the manual says to adjust the 'vertical lever' until the correct timing is reached. (this is to set the max advance...
G'Day all, <br /><br />I was reading through some of the posts in the outboards section and a couple of people mentioned hull dents causing listing of a boat and poor hole shot etc.<br /><br />I have dent in my ali runabout that from memore is about 3-4 inch long, maybe 1in wide and 1/2in deep...
Hi all. Im not sure if this should be bumped to the general boating section, but I have a '71 merc650 which is Very difficult to turn at the steering wheel. I think its the motor seizing in its pivoting mechanism rather than the steering assembly though.<br /><br />Even when I have...
Hi all, I recently replaced the impeller on my 71 merc 650 (4cyl) (see other post). On checking the engine running on muffs, I noticed water seeping out of the top cylinder between the spark plug threads :( . on pulling the spark plug out, the outer section (thread area) looked corroded so...
Hi folks, I have just changed the impeller on my '71 merc 650 (4cyl) and wondered if I should have bent the vanes in one direction (which direction?) before replacing the pump housing. I searched in the forum and in some instances its suggested that you need to, and other posts say that the...
Hi, I was just wondering if there is any need to flush the lower unit (somehow) rather than simply draining the fluid when changing the L/U oil. I was once told by an auto mechanic that you can run a small amount of kerosene in with your engine oil and that this has the same effect as the...
Hi, I have an old (70-72?) mercury 650 4-cylinder which seems to run really well- most of the time. It generally seems to start easily, even if left for a few weeks. <br /><br />The problem I am having it that when I stop the motor, then try to restart in quick succession, the motor will fire...
