1999 Air Tique 176

Hey Jeff. Looks like a fun project. Where did you get the new manifolds? Everywhere I have looked they look to be on back order (Nautique parts and discount inboard marine). I was thinking of replacing my ‘83 manifolds.

NautiqueParts just got them in yesterday.

Sweet, thanks. So it sounds like from your post that breaking the hex bolts is a big risk?

[NautiqueJeff]

Correct. We'll see tomorrow. This is the first set I have ever tried to remove.

[Skidave]

I never removed a set either. Always sold the boats before I had to replace them. I'm curious to see how you make out.

Brake fluid is also a great penetrating lube.

NO broken bolts! Woohoo!

The manifolds and risers came off fairly easily this morning. I think the ATF/Acetone mix worked well.

Now to get the surfaces cleaned up and the new ones installed.

[spenclo123]

Nice Jeff. Curious, how many hours are on that boat?

[NautiqueJeff]

Just over 900.

[NautiqueJeff]

Well, the new risers were not the right ones for this boat. Not sure if it was my error or NP's.

Luckily, the original risers were not bad, so I just reused those, and luckily didn't break any bolts on those either!

Everything is back together now, and the plugs have been changed too. We'll drop it in the water later this afternoon and go for a test ride.

I even got my son to help on this task! He cleaned the engine surfaces to prep them for the new manifolds and gaskets, then he helped lift and hold the new manifolds into place while I bolted them on, and then he gapped the new plugs.

Why did you get the smaller longer risers oops

[gary s]

Somethings not right with your pictures- 3" risers on this one-



31/2" risers now on boat-


I was thinking he's not going to be happy with the wrong ones but somehow you got them right

[NautiqueJeff]

Yeah, not sure if I screwed up or NP screwed up, but they were the wrong ones. I had to reuse the originals, but that's OK. They were still in good shape.

[gary s]

Townsend probably does not run across that many non GT40's and just thought it used the 3" risers. Correct Craft probably wanted 3 1/2 risers across the board so that they didn't need different mufflers,hose sizes and other misc exhaust parts

[NautiqueJeff]

Got it in the water this evening, and it seems to run fine. It is safely on the lift, and ready for playing around tomorrow.

[NautiqueJeff]

First run today.

I put about five hours on it today, and it is a blast to drive this little boat.

Here's the first run!

muscle boat. I dig it!
