    Going straight at low speed?

    Oh yeah , wanna give us a clue what sort of weight we are talking here :D ? Im 265 lb's, you'd think moving that lot from side to side would turn the boat fast enough to run over the skier being towed :LOL:

    Going straight at low speed?

    Yes ,when on a bicycle or motorbike , when travelling in a straight line its actually a slow weave continually correcting an out of balance situation . If you tried to ride in an actual straight line you'd fall over .

    Rubberized or Epoxy undercarriage roll on for salt water trailer?

    I would pick something that can be easily patch repaired . I have no idea whats on my boat trailer but it has stayed clean looking . Only thing I have done is cleaning and regreasing the spring mounts/ slipper pads and refilled the bearing buddies . Ha ! probly hideously rusted inside .:LOL:.

    Going straight at low speed?

    I spose its pertinent to mention free play / backlash in the steering system , coz any of that will certainly make things worse . Also there may be some gain by adjusting the trim tab/ anode above and behind the prop . Its my understanding that this cant really be adjusted to suit all speeds...

    prov 150 carb question

    Any of the ways mentioned above will do fine . They are not under any stress. When I said about wanting to look at the balls re the poor idle I meant thats where I would look to fix the idle as someone has done , not that I suspect that the sealed in balls are causing an issue now . Sorry...

    prov 150 carb question

    Different takes . I usually get a fn small drill , like .75-1.5mm depending on size of your balls (literally ) and drill into the ball about 1/2 way thru then put the shank of the drill in the hole and lever ball out . Do what you have to and then refit the ball hole facing out , maybe...

    Going straight at low speed?

    That depends on so many things . How much weight on board ? how is it distributed ? Whats the water like ? . Basically you need to experiment to find the best setting at the time . Sometimes the only solution is to re distribute weight . Smaller boats can be sensitive to weight distribution...

    prov 150 carb question

    Those balls are there to seal off the ends of internal passages. The fact that they are sealed suggests that some previous person has removed the balls/plugs to gain access to the passages for cleaning . That they have sealant on them is not a worry but if I had coughing at idle issues thats...

    Acceleration problems

    Cant make up my mind wether Id go for a set of plugs if you havnt already , but my gut feeling is that ( at least ) one of the carbs needs a good clean. I take my boat down to the river and back it in until motor is in deep enough to run and then use the river like a dyno so I can run it at...

    3 cylinder 35 hp water holes sealant?

    Those holes need a good clean. As far as sealant is concerned there are a lot of quality products out there , just pick either your favourite or well known brand and go for it , just make sure you get the right type . Permetex is one I use , and Three bond

    Testing thermostat with torch

    Um , looks sorta melted aye ;) . I would replace it not only because the threads look melted and it might develop a leak or pop right out but also because getting that hot may affect its reliable operation .
