Q:
Do you also have the starboard manifold?
A:
The starboard manifold would be part number: 18-1902.


Q:
Will this fit my 1989 chevy 5 litter port side?
A:
This fits most GM V-8 small blocks with end riser. So it will depend on your engine type. If you have model number we should be able to cross reference if you need more assistance.


Q:
I notice these manifolds only have one Bolt per port. Doesn't seem enough for a good seal. 5.8l Ford 1991?
A:
Well this particular manifold can be used for the port or starboard side and it comes with the mounting kit which contains four bolts. This fits: Ford 302 and 351 CID engines, Crusader 302 and 351 CID engines, Interceptor 221, 260, and 289 cid engines, Commander, Mercury, OMC, Palmer, Pleasurecraft & Waukesha.


Q:
I have a 3.0 liter 1992 omc cobra engine where my exhaust manifold is leaking. This product appears to fit my motor but the part number on the current manifold reads 986984. Will this product still work on my engine?
A:
Not sure what the 986984 number is, it may be a casting number, but yes this will work with your application.


Q:
Will it fit on a 327F 1968 chris craft marine?
A:
We do not have a manifold that will work for that engine unfortunately. You will need to contact Chris Craft.


Q:
How to find out what manifolds fit for my boat?
A:
It is determined by the model or serial number of the engine.


Q:
How do I know what manifolds and risers and gaskets and hardware I need for my boat?
A:
It is determined by the model or serial number of the engine.
