Bought my new well new to me boat a couple of weeks ago.....When i first took it out on the river it seemed to get right up on plane and go but i think a 85 on such a small boat should be a little better on the top end......To my best guess since i didnt think about a gps it was around 35mph......But it didnt bother me that bad.....The first time i took it to the lake with my father and nephew for fishing it seemed to be a dog and never get on plane the only thing i did differently was buy another portable fuel take and quick connect so i had two 6 gal on board......I switched back to the old tank and it got up on plane but not like it did the first time.......Slow starts and it seemed to be bogging down the wieght was substancially different first time it was me 235lbs my buddy 170lbs and his ol lady at 135lbs total of 540 with no gear.... second time me 235 my ol man 260 and my nephew 85 plus prob 50lbs of tackle 630lbs total but the boat should still run better then that i think.......I changed plugs and my buddy and i went back to the river seemed to be just like it was the first time right on plane but still only 35mph............Yesteraday we decided to take the tube and some friends to the lake......first we tried with 5 people 235 225 205 130 and 135 the boat just blew 5-10mph so we dropped two and went back to tube The boat took forever to plane but was good prob 30mph with the tube being pulled.....grdually as the day went on the boat sucked worse and worse wouldnt get on plane for half mile or so..... So i put it on the trailer discusted.....Any ideas here is what i can think you might ask sincer i read a bunch on this forum but dont know and dont have all the money in the world to throw at it......Prop says 12 5/8 dia and 21c pitch should be 13"x19" as i can find but the thing is if i pull a tape between the farthest points the prop is only 11 1/8 in diameter.....I have suzuki quick disconnects on the tank what came with the boat I only know they are suzuki because i purchased a new one for the new tank....I run 50:1 supertech oil because thats what the previous owner ran... I do not have a tacometer any suggestions on what to run and where to get one.....I put the telltale on the force like it says to in the begining of the threads. When i first changed the plugs only the bottom two were fouled black the top was still shinny gold so i threw the junk champions out and bought autolites now the top seems to be foulded just like the rest.....I have yet to do a compression test since i dropped my gauge and it reads 40lbs consantly a new on is coming this week on the MAC truck!!!I just want this boat to run right since it was just a trial boat to see if we will use it and we love it next year we will sell it a buy and inboard small block chevy so i can work on it and it will pull two tubes Thanks sorry fot the long post but i figure more info better then you asking the ques......
