Had the chance to measure the current drawn by the ignition system. It's about 3.7 amps ( ignition only without instruments) Installed the seadog switch (which is actually rated 10amp); it works like a charm.

Oh no. The Sierra that failed and I replaced with the Merc, had been in the engine for 2 or 3 years.

To wrap this up. I replaced the Sierra temp switch with Merc OEM and the issue is gone. Tip: the Merc original Temp Switch retails for about 80 or more. Instead, get the entire Audio Warning Kit from eBay for 50 bucks or so. It includes not only OEM temperature and oil switches but the warning...

Couldn't find the exact answer to my question so here is a short write-up about repairing the Audio Warning Kit. There are mixed opinions online about the time delay on the buzzer. Many like it sounds as soon as you turn the key, others prefer it doesn't go off right away. The latter option has...

I guess it depends on the type of ignition switch your boat has. My boat has a four-position ignition switch: Battery, Starter, Ignition, and Accessories. If I turn the key to the left, it enables the accessories only; this is where your radio has to be wired to. When the engine is running, the...

Spent some time troubleshooting the boat's alarm issue. Now I'm pretty confident it's the temp switch. To my surprise ( as I hoped it would), the alarm didn't go off when I turned the ignition. So I took the boat to the lake armed with a brand new IR thermometer. On the water, in neutral, I let...

Seem widely available. I just did a quick search on eBay Solenoids https://www.ebay.ca/itm/112056452576?hash=item1a1715c5e0:g:ekYAAOSwGXtXh7Sa Trim Switch https://www.ebay.ca/itm/194143708554?hash=item2d33dde58a:g:5FsAAOSwWUJgpohC Be aware that replacing the trim switch is a PIA. The outdrive...

Thanks, Chris. By fast idle I mean 1000 RPMS. At the ramp with the boat on the water and trim all down, I did bring it close to 3000. Temp sender and gauge seems to work fine based on my initial testing. IR temp gun will tell the truth. It's so strange that the alarm went off when I turned the...

No. But unless it broke out of the blue, engine was fine at the ramp and performed well all the time. And if it broke, so did the temp gauge? I'll bring a IR temp next time I get my hands on the boat. I want to think it's just the temp switch that went bad. Hopefully!

To close this topic up. I put together the engine without messing with the carburator nor the timing. The engine runs like a champ now (Pat myself on the back for adjusting the valves first time right 😉). No more rough idle..it's super smooth and quiet. Power is back. At this point I strongly...

And yes, trim limit switch is another possibility. Turn the drive all the way to starboard and check the cables aren't broken (mine broke long time ago,). If they are, then bypass the trim switch limit cables inside. If it still doesn't go up after that it's either the UP selenoid or the pump...

If it goes down but not up, then the fuse isn't the problem. There is only one fuse feeding both selenoids. I once experienced something similar. The relay or selenoid contact was all rusted...mine stopped going down, not up. I took apart all the selenoids and the copper bar...cleaned them all...

Hey folks, 17 footer 1992 Cadorette bowrider 3.0 Merc 1998 Alpha one gen one. Need your input here. I just replaced the blown head gasket of my 3.0 (reconditioned/resurfaced the head and had the block's flatness verified) and I also replace the ripped exhaust bellow and installed a brand new...

An update here. I had the head resurfaced. The engine shop guy said the head was in pretty bad shape. Also, he's 90% sure the head's imperfections blew the gasket. The block is as straight as it could be. I guess if the engine went 60 hours with a messed up head and rev abuse, it should last...

The boat is 17 feet; 2200 pounds (According to nadaguides). Max rpm is 4800 (now I know) Drive ratio...not sure it appears to be 1.94 Max Speed on my GPS Speedometer ~47 mph. I normally cruise at 30-35 mph.

Thanks. As soon as I install the head back, I'll find another tach and run it parallel with mine...I hope that explains why I thought I was doing 5500.

I don't understand. What's wrong with running a 14.25/21 on a 3.0?

Forgot to mention...it runs a 21 pitch prop.

I don't know. It's been the same since I bought the engine. Never had to adjust it...as said the engine always ran "perfect". How do I check that?

Thanks for the tip. I thought the WOT was 5800. In any case I've brought it to that speed maybe twice in perfect mirror lake conditions. I normally cruise at 4500 max. So you don't think the fuel mixture caused it? I'll look for those bolts
