    Stumbling at Cruising Speed - OMC 5.8L

    OK... dwell set to about 28 degrees, timing is 10 BTDC, coil replaced, belts replaced, and took it for a test drive. Not getting the stumbling at cruising speed, but still having the issue where is starts great on muffs, idle set at 800 rpm. I get it on the water, starts great right away...

    Sorry, that was confusing on my part. I had the port side manifold off for other reasons.

    Stumbling at Cruising Speed - OMC 5.8L

    OK. Got the dwell meter. What is the best method to set dwell? Can't really adjust the points with it running like other models, due to the distributor cap, unless I'm missing something

    Thanks... No way the mice took that. Odd that it ran fine last year... assumingly without it. I ordered a used one on ebay.

    OMC 5.8L Screeching, Power Steering Pump?

    Tried this. Didnt seem to change the noise much at all, but belts are cheap so Ill replace. Power steering fluid level was fine.

    1986 Mercruiser 260 (GM 350) Cracked Block?

    Well I dont want to spend a ton of money, but if I rebuild the engine with a new block I am probably above $1500 as I will probably end up replacing most internal engine parts. So if its under $4000 to upgrade it may be worth it to me. It looks like it may be much more than that. Any go to...

    Am I missing a filter/arrestor? 15hp Mercury Kicker motor

    1986 Mercruiser 260 (GM 350) Cracked Block?

    Yeah... I kinda figured... Is this a good time to upgrade to FI or something bigger that is a drop in? Or just stick with the same engine, new block?

    1986 Mercruiser 260 (GM 350) Cracked Block?

    Been rehabbing a 1986 Carver Santa Cruz and got the engine running and was testing the cooling system and it leaked a ton. Most were due to loose hoses, but I think I found a crack in the block. Just want to confirm this is not a seam where there should be a gasket that may have failed and it is...

    1986 Carver Sante Cruz 26' - Advice

    OK. I'm going to take a look with a bore scope and see if i can find it. I think it probably was a burst line during winter.

    1986 Carver Sante Cruz 26' - Advice

    Has anyone dealt with a leak there or knows if there is an access point? Maybe it's a plug removed in the winter?
