    Random overheat returns

    1985 carbed 260 mercrmercruiser and alpha 1. New stat and impeller in April. Took the wife out for a quick little run today and noticed engine was losing RPMs. Glanced over at the gauges and noticed temp was almost in the red. Pulled her down to an idle and immediately stalled. Opened hatch and...

    Over-propped?

    New to me 1985 250 sundancer with alpha 1 and 260 Mercruiser. She doesnt give me more than 3800 rpm's and currently has a 4 blade prop which o suspect is not stock. At about 3000 (where i like to run her) i can trim up the drive and trim down the tabs and get about 27 mph out of her. Once i...

    Which heater hose?

    I want to replace the hoses to the manifold risers and what I have now is gates red stripe hose. All I can find online is green stripe. Will this work and is it acceptable? I don't know if the PO installed it or if it's from the factory stock. 1985 260 Mercruiser.

    1985 260 overheated

    Okay, ran her for a few hours on Sunday arpund 1200 rpms and about 3200 rpms for about 10 minutes on the way in and the needle never moved. I've been suspecting a bad thermostat. Today I let the wife drive and she says "hey they temp went up some". Yeah it did, it was pegged and the damn plastic...

    Looking to buy 2 bank charger...

    1985 250 Sundancer with 5.7 V8. What does everybody prefer as far as brand and any suggestions on amperage? I'm assuming 20 amps but maybe that's unnecessary and 12 would be sufficient?

    Expected fuel consumption for 268 sundancer with 5.7

    The wife and I want to move up from our 18'6" seville and the 268 DA is a nice fit for us. I realize this is an EXTREMELY broad question but how bad is it? I know it's night and day from my little 3.0 seville but I don't want to make a move I instantly retreat and end up with a boat I can't...

    Can I (temporarily) run with open thermostat?

    1984 mercruiser 140 3.0. The stat appears to have failed open and I can't track a new one down today. It typically runs about 140ish degrees and now it's about 110ish degrees, I suppose. Not the most accurate gauge but do these numbers sound about right? Anyhow, I can feel warm water on either...

    How to seal cork valve cover gasket

    Gotta check the old girl ('84 3.0 merc) for loose rockers tomorrow and I plan to do it while running. I picked up a quicksilver cork gasket. Do i need to put some perfect seal or rtv on the gasket? One side, both sides? Really hoping to find a loose rocker so I can get on with the season. Any...

    Possible to adjust rockers while engine is running?

    1984 3.0 mercruiser. I have some "clacking" and I'm pretty sure it's the rockers. Can I adjust these while the motor is running and can anyone suggest some better fasteners for the rockers? Thanks all,. Anchors aweigh!

    Lower shift cable question.

    I need to order a lower shift cable and after searching the forum and the interwebs it's still clear as mud what I need. I've read about "fore and aft", "old style or new style" "opposite side of bellhousing", "drilling and tapping" holy cow! Fwiw I have a 1984 pre alpha (pre load pin) that I...

    Alpha lower with pre-load pin...

    Is this possible? I did the impeller kit today and it was odd that the impeller base didn't fit. Sierra #18-3320. The shaft has the pre-load pin on it but the lower half is visually an alpha.

    Grease fitting locations.

    First gen alpha. I have the drive off so i can do the impeller tomorrow. How many grease fittings are there? Also, i picked up some super tech marine grease at Walmart for the wheel bearings. Can I use it to grease everything on the drive as well? Thanks!

    How to cover gimbal housing

    Finally got around to removing the out drive for the winter. As a first time boat owner I'm curious as to how everyone covers the exposed area after removing the sterndrive.

    Can sterndrive freeze and crack?

    Hi guys, first time boat owner as of September. I'm confident I winterized the block and exhaust manifold by draining and filling with -60 anti-freeze. I pulled the hoses off either side of the thermostat housing to pour in a/f and fill her up. My only concern is the fact that I didn't use muffs...
