For what it's worth for Mark l owners the riser will work but one has to re-invent the wheel to make it do so. Although the part will fit it is the hoses that make it difficult as to where the aquatank muffler is located. I decided that it wasn't worth the effort especially in light that my schedule 80 black Iron nipples worked and lasted me 11 years. I was surprised to find the integrity of the nipples in much better shape than than I expected when I removed them. Ugly on the surface but still had a lot of meat and the thread were in tact. Still I would strongly recommend to change them out sooner than the 11 years I waited to do so. Even though the riser was still working metal fatigue should also be considered. Schedule 80 nipples and fittings will run about $30.00. S.S. is great but at what cost?? I love my Catalina but it's not a Hinkley.

Last year I replaced the riser on my M25XP.  I got the riser from Catalina Direct.  They had exactly the right size (no cutting or adapting needed) and the silver insulation.  The unit comes with the hump hose as well as the insulation.  In my opinion it's better than trying to assemble pipe, nipples ,etc.  The Catalina Direct website gives all the information you need to order the correct riser.

Hope this helps,

i am familiar with Catalina Direct. I doubt they will have the correct riser for my older Catalina. I did this same job 11 years ago with black iron and schedule 80. I should of replaced it again 5 years ago. with the insulation covering it was out of sight and out of mind. Any way the riser kit is a vast improvement but was hoping to see if anyone has done the upgrade using to an older Catalina Mark l. I'll find out this weekend when i will be on the boat to do measuring.

Asea : The riser will probably not fit unless it can be turned sideways and I don't think it can function sideways.  You'll have to measure and Ask the question.

My thought

yes, i will have to measure, i was just wondering if anyone has done the upgrade. of course it won't work on a sideways installation.

I have to replace my exhaust riser on my 1986 catalina. i was told instead of using niples that westerbeke makes a riser for the universal engine m-25 part number is 200266. it looks easy to install but i was wondering if anyone has done so? i wanted to make sure that it would physically fit. Attached is a picture of the part.

Thanks

I appreciate the input. I am just exploring at this point. My diesel does run fine. I just would like a little more power. I do have a 2 blade prop and maybe changing just that might be the way to go. I need to get info on the self adjusting props and find out if they work as well as they claim. So it looks like I have some homework to do.
Thanks all

I'm looking for info regarding re-powering. I have a M-25 and it does work fine, but am thinking of dropping out for a couple of years with the wife and would like a little more H.P. I was looking at the M-25XPB. Has anyone done this and if so is the transmission compatible?

I am doing an electrical upgrade on my catalina 34. I have read similar projects listed under projects on the catalina international web site. there are 3 posted and all 3 have excellant info. Still I would like to contact the authors. They have their names listed next to each article but no e-mail address. Is there a list that I can find their e-mail addresses

I have a 1986 Catalina 34 Hull #101. She is in good condition. My wife and myself are thinking of taking her around the U.S. starting from New England waters sailing to the Pacific North West by way of the canal. We do plan on upgrading her for this kind of voyage, new standing rigging, inner forestay, wind generator, refrigeration, epirb, life raft.,etc. I know that our boat is not a blue water cruiser, yet we don't plan on crossing any oceans. I was wondering if anyone knows of a Catalina making long passages like this. On the voyage web page I saw those that went across country trucked their boat. I would appreciate any comments on our plans.
