I would like to know the hight measurements of gill magnum choice risers. I am having a clearence problem with my tail pipes fitting under the deck part of the gunnels on a twin set up.magnum choice risers look like their lower. I was thinking of welding inner and outer pipes and make a dry set up. Need the measurements from the bottom of flange to the highest part of the curve on tube. I need to know this before trying to find and buy two sets Any info is greatly appreciated. Keith

Hope you find what your needing, Keith!

Rex Marine used to sell the lowest stainless riser for GIL manifolds that I have ever seen. In fact I bought a pair for my X-18 Donzi since nothing else would fit under the hatch, and it was lower than GIL's lowest riser. I think it was actually Rex Marine's silent choice riser. Other than that Brownie (Allen Brown) at Stainless Marine can build you a custom pair of risers for your GIL manifolds and they will be much more expensive than the Rex risers, but on the other hand, you will have exactly what you want.

I have these and can measure them tonight. Give me an hour.

Hi Jeff, You trying props this weekend? Let me know results. Forrest thanks for info.I'll check their website and check them out. Formula31,that would be great thanks. thanks again guys Keith

It will have to wait till morning. We had some crappy weather go through and I dont want to uncover till morning. Let you know then.

Installed with the turbulators they are 5-1/4" from the top of the manifold flange to the highest point of the elbow. Figure 5-1/2 for clearance.

Thanks Formula31, I think with some alterations and a lot of luck I will be able to fit them. Anybody have any that they would like to sell. must be gil magnum choice risers. Thought I'd ask before calling gil. Thanks again Keith

I looked for a long time before I found a set to go along with the set I already had. And they arent cheap. Good luck. Keep posting and somebody might have a set somewhere.
