A happy boating Admiral definitely makes for easier access to boat work funding!:D

i came close a couple times :facepalm: the boat runs so smooth she walks around not holding on to anything and i got the notion to slow for the no wake zone and she allmost took a spill, then it seems every time she would be rooting around messin with stuff under the bow we hit wakes and she would bump her head on the dash:rolleyes: so i'm yelling out now any time something is about to happen trying to watch her and watch for logs and jet skis and other boats and reading buoys:facepalm: its kinda stressful i wish she would just sit down and hold on so i would have that one less thing to concentrate on

Maybe you need one of these, tell she doesn't have to follow the last one but the other three are good recommendations.:D

Re: 1968 Larson All American

i have been on the river two sundays in a row now all day this past sunday, anchored for a while watching other boats noticed when they start off the bow goes way up in the air, mine does not only comes up maybe a foot, could my trim be set wrong i had it set on the first hole as last time it was in the second where the po had it and the prop would slip some when on plane, so i thought maybe it was in the second to make up for the rotten transom bowing out some:confused: this time i tried it in the first hole all the way down the prop didn't slip and it seems to do ok, when i was a teen on my dads boat i remember his boat would start like the others i see and climb onto a plane when it got up to speed, on this boat the only indication that im on plane is that the large mound of water behind me dissappears is something wrong why am i not doing wheelies like the other boats when i take off:confused:

Re: 1968 Larson All American

Maybe your boat doesn't sit in as low in the water and just gets on plane quicker than the others you watched. As for setting the trim you'll almost need a tach or maybe a speedo app on a smart phone. Then you can play with it until can find which setting gives you the highest rpm/speed without the prop ventilating or porpoising.

Might get more help if you could get some drive by video from shore of how it rides. Might even help to take such video upstairs to the general questions sections as I've seen many get help up there for the same kind of problems.

thank you, i will make video next time, to me it seems as if i am plowing through the water now even had a little splash over the bow when i hit a large wake but when the trim pin was in the second hole the prop would slip and tach would shoot up to 6 now it never goes past 5 and most times wont go above 4, also had 1 more person last time and leaned to the side alot had to make 1 change sides to level out

Re: 1968 Larson All American

Maybe those other boats have PT&T on their motors which gives them a full range of control over propeller thrust angle. Without that feature on your motor, there will be a compromise during some phase of the operation. You just need to try all settings until you like the overall results.

I looked at posts #52 & 65 in this thread to see if I could tell how your motor is mounted in relation to the bottom of the hull and could not tell. Could you post a picture looking forward at the anti-ventilation plate with maybe a yardstick against the hull so we can verify the alignment and height? My impression is your motor is mounted too low but it just may be the previous picture angles. Good luck!

1339710274940.jpg1339710045400.jpg hope these pics help :confused: i don't have a yardstick and no one to hold the tape for me i hung it from the top of the transom, not sure if this is right the po had the pin in the 2nd hole i tried that and it looked as if it was mounding water behind me so i moved it to the first now it plows thru wakes before it would hit harder goin over wakes

Re: 1968 Larson All American

Thanks for the pix! It does look a little low to me. You have adjustment holes available in your transom bracket so IMHO you should go up one hole and try the boat again. Also, the trim pin setting in the pictures almost certainly will produce a "bow down'" attitude. I would recommend you set it as close to parallel to the bottom of the boat as possible before you go out. Good luck!

Re: 1968 Larson All American

The gurus over in the Prop Forum might be more helpful than me. I am certainly not an expert. However, it is pretty normal to recommend raising the motor height one hole and then try all the trim combinations to see what happens. Continue to raise the motor and test until it is at max height or produces lots of problems. You should be able to tell what is acceptable performance or needs to be lowered by one hole. This is a trial and error process and not some absolute cause and effect procedure with predictable results. Good luck!
