    Thanks Ron!

    Thanks Ron for that Ebay link. Very nice IMP! Was interesting to look at since that boat is very similar to mine. Same green and white color scheme. I own a 71 also, but is 18ft instead of 20ft. Also, mine has a full windshield instead of a split dash and windshield. The upholstery has been redone so is not the original green like that boat. But very cool to check out what my boat would've been like original and mint. Thanks again!

    IMP on Ebay

    Hi Dot,
    Glad you enjoyed the pictures. That is one beautiful boat.

    Well I got me an IMP. It is a 1968, I was told, 20' Hardtop. Don't know what they called it, maybe someone out there can tell me the model name.
    Ser #KH201002. It has a Mercruiser 250 cid inline six and 160 outdrive.

    The engine is shot, the tandem axle trailer needs one axle, the sides of the hardtop need replaced, the outdrive needs gone thru, cleaned, inspected, new gaskets and seals and the rest is cosmetic work. Not bad for $345.00.
    Had to go to Salt Lake to get it, 450mi. Boat and trailer sold new in SL.

    I am going to build a 250 for it with alum dual, single brl carb manifold, HEI ignition, propane pistons (10:1), larger intake and exhaust valves, hope to increase valve od by a 1/4", ported polished and relieved to make it breath better.Expect to get 130+ net hp @ 3800 rpm with proper prop. It will also have a closed cooling system with a 4"x31" heat exchanger, oil cooler and p/s cooler. Heat exchanger holds 2 gals of engine coolant, should be more than enough for the 250. Going to add P/S assist to the O/D, easier on the arms. Boat also has hyd tilt and hyd trim, adj outboard bracket.

    Nothing like having a hole in the water to throw money into.

    Ron

    Repair manual

    Hi Jake. I've got a manual for my 1984 IMP Aztec that might prove helpful to you or anyone else. Mine carry's a 228HP GM motor and OMC outdrive. The boat is currently stored under a T-Hangar in Aguila, Az. We still have not hit the water but it was only HOT weather that is holding us up. We're replacing the tilt motor, fuel guage sending unit and adding audio and speakers, then we'll head in to Phoenix to a upholstery place to have carpet installed. I do need a new power & shift control unit. The handle on top is missing and while I can use it, it's kind of awkward. Have not yet found a replacement unit that is comparable to the original. The manual is in the boat at Aguila and I'm currently in Phoenix but next time I'm there (probably late August) I'll bring it home with me so I can tell everyone what info it contains.

    Ron-
    Yes that was a very nice boat. Thought she sold for a lil low for the condition it was in, but I guess they might not have had a demand for that old of a boat if they needed cash now. I didn't catch your link until after the auction was over, but was pretty neat to look at. Wow your boat sounds like quite a project! But you seem to know your stuff when it comes to boat motors. Good luck and let us know how she turns out when you're done.

    John-
    I might be interested in looking at your manual for your '84. I'm in AZ also, near Prescott. Mine is a lil bit older than yours, a '71 but some of the info might still be the same. I'm guessing that since it's stored in Aguila that you must do most of your boating at Alamo. Have been there several times this year with ours. Much fuller right now than normal, fishing was great. Let me know when ya get your manual, I'm curious to look at it possibly. Is it real lengthy? Or could ya run me off a copy? I'll pay ya for copy and postage. Let me know. Thanks!

    Dot, the book is quite thick. But, I'll see what it would cost to have it copied and get back to you. Write me at nadaboring@cox.net if you want. Actually, we haven't got our boat in the water yet. But, Alamo or Pleasant will be our choice for regular fishing. After the dove hunt on Sept. 1 we plan to take it to Lake Powell for a week of fishing and relaxing...

    Mercruiser Manual

    Hi Dot,

    I have a complete Mercruiser Service Manual, published in 1973, like new. It
    covers everything that Mercruiser mfg'ed up to then, including engines, outdrives, wiring diagrams, steering and controls, ect. If you need information that I might have, drop me a line at freeidaho@citlink.net and we will figure out some way to get it to you.

    John and Ron-
    Thanks for the replies guys! Well I just wanted a manual to have on hand. We didn't get anything with the boat and thought it would be nice to have. The boat runs great right now (knock on wood LOL!). But would like to have something for the future to troubleshoot if we ever do have problems. I will admit that we are some what ignorant when it comes to boat motors and know even less about the workings of outdrives. I just want to make sure we take care of her so that it'll last us for many more years. I know it has an OMC outdrive and believe that the motor is OMC also. Don't know the HP or anything more. Ron, is OMC the same as Mercruiser? Did you both get those with the boat or did you buy them? If you bought them maybe I could look into that option so that I don't have to inconvience you. If you did buy them, from where? I have looked for info online and have found very little.

    John-well hope you get a chance to get in the water soon. But I hear ya on waiting til it cools down. We've even had 100 degree days up here in the mountains. Powell sounds like a good plan to me. Beautiful lake and going in Sept. will be the off season for the tourists!

    Thanks for all your help guys! Appreciate it!

    IMP Boats

    I just joined this group and saw the discussion on IMPs. I just purchased a 1970 INCA. It is a 23 footer, had a 327 originally, but owner switched to a 1981 350 Chev Truck engine a few years ago. I bought it from the original owner, and he hated to part with it, but just didn't use it anymore. He gave me the books that came with it, and I plan to scan them and save to a disc in a PDF format. I don't think I will be able to get to it for a few weeks, but if anyone is interested in a copy, I will supply for the cost of material and shipping. I want to refinish the boat, and am looking for flooring alternatives other than carpeting. I would like to go with something similar to the original, I think what is there now is the original. It appears to be a thin vinyl sheet glued to the floor and is a woven reed pattern. Any idea where I can find that material or similar? I have tried the local flooring companies and the home improvement stores with no luck.

    Oh, I forgot to mention, I am looking for a trailer for this boat, and will drive to get one if necessary. I also need help if anyone knows what the 1970 Inca weighs, I need that info to identify the proper trailer, hoping I can get it without pulling it out of the water and weighing it.

    Imp

    I am going to look at and probabley buy a 20' IMP Cuddy Cabin today. It is going to be a project boat. The inside is pretty rough, it looks like it has been setting out in the sun for a while. I was told the motor (V8 350) has been rebuilt, with 0 hours on the rebuid.
    I know these are heavy boats, how are they to pull? I have a 96 Dodge Ram 1500 with a 5.9LT V8.
    Any other info would be great.
    Thank you,
    Emmett

    Emmett that Dodge should have no problem towing that boat but I have a freind that has the same model and he had 3 trannys put in it before it hit 100,000 yet he uses it to haul landscape equipment.

    I have a 76 IMP Aztec and just pulled the original 302 out and planned to rebuild another 302 to put in but when I pulled the motor the fiberglass under the motor compartment was cracked and upon further inspection I found that there was water under the fiberglass and seems to be rotten. I am determined to get this thing in the water some day and need some info on what to do. Can I remove the motor compartment and reglass under it? It seems like it will be a very demanding job if anyone has any advice please reply!

    Hello Dot.
    OMC and Mercruiser are not the same. My last boat had a 120 HP Merc, and the outdrive from it, and the OMC on the IMP are completely different. I have the manual for the 70 IMP OMC motor and outdrive, (actually it is labeled for 1969 but apparently the same) It is the service manual, and covers complete breakdown and rebuild. I also have the Stern drive parts catalog for the 80, 120, 155 and 210 HP OMC, Evinrude and Johnson. I plan on scanning each of these, and saving in a PDF format. I will then transfer to a CD to store. Let me know if you want a copy. I will get to you for cost of mailing. Will be a few weeks before I can get to it, but once I get it started, it will only take me a couple of days to finish it. Parts catalog is 82 pages, and Service manual is about 3 times that size.

    Latch-

    That sounds great! Thanks for volunteering to take on that task! LOL. No rush, just whenever you get to it. Like I said before, I don't really need it right now but would like to have for reference when I do! Let me know when you get it done. Thanks again!
