Can I also use adhesive and adhere to be manifold surface first and then bolt on manifold or is it better to attach gasket to engine surface first?

You can attach the gasket to either the engine or manifold.

Can anyone tell me the torque specs for tightening manifold and elbow bolts?

mmwjr · 05-04-2015, 04:51 PM

25 ft-lbs for the manifolds and 33 ft-lbs for the elbows

Mine just came in the mail. Not looking forward to carrying those down to the boat,and carrying the old ones up. 2 flights of stairs for me.

Put on new manifolds and riser elbows. Pretty straight forward and no issues. Ran boat a few minutes and left riser still running warmer to touch than right. Although I know the temp gauge is not best indicator, running at normal temp. Have not used a gun on riser yet. Just wondering if it is possible that one side might run warmer naturally. Obviously it's not an obstruction issue given everything is brand new.

Any thoughts?

Not uncommon for one side to be hotter than the other. I think it is due to the distribution of the t-stat housing not being equal.

So nothing that I should be concerned about?

mmwjr · 05-09-2015, 05:27 AM

As long as the elbows temp is not above 140 - 160 F

So, you may have answered this with the t-stat housing, but if it does intact go higher than 160, given new everything, what should I now be looking at? Do you mean a thermostat problem?

mmwjr · 05-09-2015, 02:28 PM

If the t-stat was bad you helm gauge would be reading high as well, is it?

One thing at a time get a handheld IR sensor and get some reading before guessing

Took boat out this morning and ran really well. Only issue, happened only once, boat at idle began to sputter a bit and died. Restarted without issue. After it shutoff, there was an alarm going off. Once started, it went off and didn't happen again. Got back to dock and restarted a few times, put into neutral and idled fine.

I was told once what that sound Afghanm alarm was but have forgotten.

Probably low oil pressure warning as ignition was on but no oil pressure once it died.

Had a friend tell me that the alarm sound could be the neutral switch on the throttle linkage, maybe grounding out?. Could have slipped out of adjustment?

Neutral safety switch, safety lanyard, nor shift interrupt have anything to do with the alarm nor is there wiring close to short out.

Alarm is either low gear lube, low oil pressure, or hot engine.
