    Dot and Emmet and anyone else looking for a copy, send mailing info to me at larrylachat@hotmail.com and I will get it out. As I said, it will probably be a few weeks b4 I get it done. I am still looking for information on the weight of the boat, and still looking for a trailer for mine. Any help is appreciated. If anyone out there has a 70's Imp Inca, I need info so I can get a trailer for it.
    Thanks.

    I got a 76 IMP Aztec im now tearing totally down. I got the motor totally stripped and am now working on removing the flooring and replacing the stringers and possibly even the transom but im hoping for the best. You say you got a 350 chevy I have a 302 and was wondering what danger there would be to my outdrive by adding horse power if any? If you got any tips let me know or if you got any questions send em my way maybe I could help.

    1976 IMP Pawnee

    Hi ship mates.
    I 'm glad that so many of you have enjoyed your IMP as much as we have. I am the original owner of a 1976 18 ft. Pawnee tri-hull. It has the 302 V-8 (233 hp) merc. (425 hrs.)and it has been the most reliable boat I've been around. This boat still has the original interior (clean back to back seating) along with the original factory fitted canvas tarp. It is a heavy boat that can pull a large adult skier on one ski. I recently blasted and painted the tandem shore station trailer to match the boat(maroon/white) and have nearly new tires on it. I have also added a teak wood swim deck for easy in and out of the water and a depth finder. Mechanically A-1 shape. Looking to sell this boat, pictures available, drop me a line. Can be seen/driven in central Ill. rbdb80@yahoo.com

    IMP Refit

    grgoyle1229, I have stripped the interior of the boat out, except the flooring. It all seems pretty solid. I am going to redo all the interior back to the original (the best I can anyway). As far as uping you're HP, I don't know about that. I won't have to do to much to the motor, it was rebuilt before I got it. I will have to take the outdrive off, to replace the transom seal. At this point, it looks like all I will have to do is some minor fiberglass patches from some chips. And redo the interior, and paint. I am not going to get in a hurry to do it. I want it to come out nice. I have never done anything like this before, but this boat just looked like it had a lot of potentol (sp).

    I unfortunately have alot of rebuilding to do. It seems the more parts I check the more I have to replace. So much I wont even attempt to list. I have found some good sites for parts though like aftermarket discount marine they have huge inventory and seem to be moderatly priced but if you know of somewhere better do say. I have to tear up the flooring and get a good look at the stringers hopefully they arent bad but I know better. Ill have to remove the inner hull and go to work if they are. Im really just looking forward to building the motor. I purchased a 351w which has the same bell housing pattern as the 302 that was originally in the boat. Which is why im worried about the outdrive being able to handle the extra hp. But I guess trial and error are the true way of man so Ill let you know what happens.

    Outdrive HP

    Hi All,
    Mercruiser outdrives are rated by HP, 140, 160, 165 on up. The upper and lower housings are pretty much the same but the gearing changes as HP increaces. Your outdrive has to match the HP of your engine. Fine tuning of the WOT will be determined by the dia and pitch of the prop. It's better to over build the outdrive than the engine. Cheaper in the long run as outdrives are spendy to rebuild.
    Haven't gotten into OMC or Volvo but suspect they are much the same as Merc.

    Is there no way to check the stringers without tearing up the entire floor? I would like to check mine, but hate to have to pull up the whole floor, if unneccessary. Would appreciate the URL to anyplace that has material or parts for sale for our boats.
    Thanks

    Good Morning all. I'm new to this forum and pleased to see a group of I.M.P. fans gathered to discuss a great boat. I recently acquired an X190 with a 305 V8 carburated Mercruiser. I LOVE this boat and the work it's taking to get it ship shape.

    Here's a question/comment. A number of years ago a friend of mine owned a Wellcraft 190 Classic built in the late '80's. I would swear that his hull is identical to mine, right down to the layout of the cuddy. I even want to recall that the USCG plate said I.M.P. on it which didn't make any sense to me at the time. I really liked that boat too. Did I.M.P. build hulls to be rigged by other boat manufactures?

    IMP Inca 23 ft

    I'm sure you have gotten several responses on the weight for your 1970 Inca. I have a 1974 model and if I'm not mistaken the data plate shows the weight of my boat at 5400 lbs. I hope this will help. These are heavy boats.

    Thanks,

    Rebuild

    grgoyle1229, I don't have as much tear down as you do. I have the interior all torn out, the floor is in good shape. I am patching fiberglass today, and sanding. Then I will take off all the crome items and get it ready to paint the top (above water), then carpet, and the rest of the interior. That will take a while, I can not work on it very fast. I have a very bad lower back, so I can only work on it a little at a time. I don't have an outlet for aftermarket items, I have been looking at West Marine. They have quite a bit of stuff, If you don't mind I would like to know what sites you are getting the after market items from.
    How is it going with you're rebuild?

    I don't know if this will get to you or not. Here's go's again..... I have a 1974 Inca and the data plate reads that the weight is 5400 lbs. if I remember correctly.
    I hope this helps.

    Thanks,

    I'm new at this site, I have a 1974 IMP Inca 23' hardtop. I would like to know if anyone has ever did an engine swap by installing twin Mercrusier 140's or Volvo, etc. Can it be done? Any information will be helpful.

    Hi,I am new on this message board. I have just bought a Iola boat model INCA 1969 cuddy cabin 22.5 feet. The orginal motor has been replaced with a 1989 Corvette engine. My question is the side windows are missing. What type of windows was used originaly? I am going to have sliding windows if possible. But, I would like to have some suggestions on this matter. Also, I have replace the canvas top and the bottom needs some work on it. Should I have all the wiring replaced since it is such an older boat? I was amazed as to the remarks about the IOLA Boats and there durability on Lake Erie. I have always been a lake Erie fishing person. Sincerely Tom
