Starboard Motor running hot and having hard time shifting it.

[suss1173]

I recently picked up a Pachanga 27. The boat has been in fresh water most of its life (Naples ME). I am using her on the Long Island Sound (salt water). When I put her in on Friday I ran her for about 3 hours, and she ran great. Other than a loose solenoid wire, which prevented her from starting, I was able to fix it at the dock, and she was flawless.

I went out yesterday for my second voyage and noticed the starboard motor was running hot. The temperature did come down at slower speeds and after idling at the dock it returned to (almost) normal temp. When cursing at 3,000-3,200 rpm she was close to 200 (on the gauge) and at lower RPM's around 1,600-1,800 she ran a few degrees cooler, but still hot. however, I let her idle at the dock for about 5-10 minutes and she came back down to 145-155'ish.

It was very hard to get that motor in and out of gear. I doubt these issues are related, but am looking for some advice on where to start looking into them. I don't have experience working on marine motors, but I am mechanically inclined. I do my own breaks, rotors, plugs, oil, trans and diff fluids, on my cars and willing to take on DIY projects.

Is it likely that the shifting has something to do with the transom service recently done (two weeks ago)--new bellows, shift cables and gimbals?

The pictures of the temp guages was running around 1,600 RPM. Any guidance on the above issues would be appreciated.

Re: Motor running hot and very hard to get in and out of gear

Running at normal temps at the dock, but increasing temps as rpm's and loads increase, is usually a symptom of a bad impeller.

A hard shifting outdrive can be a shift interrupter switch mis adjusted or bad…..or a symptom of a cable adjustment or crimping/tight bend in the cable.

This much wrong in seemingly unassociated areas would seem to point in different directions; however, you have a common element here: somebody did a major outdrive service that entailed removing the outdrives. Such service should have included new impellers and if the cables were replaced, then I wouldn't think there would be a shifting problem. I'm thinking I'd start with the mechanic that supposedly did all this work for you.

Re: Motor running hot and very hard to get in and out of gear

give or take thats about 212 degrees and you may have damaged the cable where it passes around the exaust Y pipe.
It tends to melt . Follow the cable to see if you feel a flat melted area by the Y pipe

Thanks for the replay. Any chance you'd have a picture of what I should be looking for. Of not, I'll google it or just start poking around in the engine compartment. Tomorrow.

Thanks again.

Listen, If some one did bellows shift cables etc. You need to see them and say this is not shifting properly!! American Express is my freind because when there is a problem you can call on them for help. Stand behind your repair. After that then we can deal with the hot motor issue. Hope this helps, keep us all informed.

Dan hit the nail on the head in regards to shifting. That's a perfect place to start.

As far as the overheating, it could be an old impeller, worn impeller, or one that got damaged from sucking sand/debris. That's about a one hour hob to replace. However, before you do that, check to see what the physical temps are at various spots on the engine. We need to see if the problem is indeed "getting hot", or is there a problem with the gauge. Things you can easily do:

-- Feel the top of the elbow with your hand - it should be warm, but not hot. It is normal to feel a slight variance from port to starboard manifold. But the temps from port to starboard engines should be very similar.

-- Take measurements with an IR gun - at the t-stat housing. Again, compare.

-- Swap temp gauges and see if the problem follows the gauge or the engine.

I ran the boat for an hour on Wednesday and same on Thursday and the temps did not move above normal. The water pumps are 4 years old, so I wanted to change them anyway. The ones that come out did not look too bad so I'll keep everyone posted on temps.

Regarding the shifting. It turns out there was very little to no lube on the U-joints and on the shift cables of the Starbord drive (they pulled the drive off vs just the lower unit). The shop said they are confidant that was the cause of the shifting issue. The transom service was done by Naples Marina in Naples ME (Where I bought the boat) and I am in Long Island. So its not realistic to get the boat back to them. I did call them, but they did not seam interested in doing anything (lessen learned). Just sucks that I'm going to have to pay for an additional 60 to 90 minutes labor as I've asked them to pull the drive off the Port motor as it's likely not properly lube either. The work is being done at Quality Speed Marine in Glen Head, NY (Skip).

Typically I am a DIY kind of guy, just wasn't able to budget the time to tackle this project. I hope to get it back tomorrow and will keep everyone posted...
