i have thoses but when there is two people up front and two people sitting in the stern chairs she WILL NOT GET ON PLANE. every body has to stand up front and i would like to make it more comfy for them so that why i need the double back seats. * until i get an engine with more power it terns out in sted of 225 i have a 125 horse power i/o they made a typo on the regerstration.

Re: New Dash
 

When I got my boat It had a 165 mercuriser I/O which was close to 120 at the prop.

But with a 15 X 15 1/4 prop I use to get on plane with 8 people on board, it was slow getting there but it would do it.

What are you turning for a prop?? Thats why I have aways used that prop even after I switched to OB, and more HP.

Re: New Dash
 

i loved my old engine but i had to replace it one day because it through a rod. i did't now that the measured at the engine and not the prop do they still do that or has that changed. so i dont know if that rating is at the engine or prop but i still will never get on plane the top speed i can get is maby 14 knots with me at the wheel and two people in the back. but even if i got the back to back seats do you still think that it would not get on plane with every body sittin up front. o and i stated the dash board i will post pics of the progress later this weekend.

Re: New Dash
 

I/O HP is at the prop not the motor.

Old O/B was also at the prop, but todays O/B motors are HP at the motor.

I still think you should reprop? Will get better, but still going to have issues if your motor is that small, and that many people on board.

Re: New Dash
 

ok i will look in to that issue with the prop thanks hro the hp info i will keep that in mind when motor shoppin.

Re: New Dash
 

MJ, I think you got her bassackwards. Todays O/B hp is at the prop.

Re: New Dash
 

Good eye there, Yeah you're right Sea

Re: New Dash
 

Thanks guys I am backwards should be the other way around!!

I had a ruff day yesterday and today not looking much better :(

Re: New Dash
 

Fishbone...what prop you got??...even w/ only 120hp she oughtta get up on plane and stay there w/ several people on...have ya got a workin' tachometer and do ya know the MAX recommended RPMS from the mfgr?...sounds like your motor in bad need of tune-up or other repair OR boat needs re-propping OR both... ;)...are ya gettin' fire on all cylinders?...

Re: New Dash
 

not sure what prop but the engine has only got anout 20 hours on it would i need a tune up or is somthing else wrong but about the cilinders my last engine it was a six cylinder and this one is a four cylinder and it is the second new engine i have tried. i only had to pay for one but the first one i had that was the problem it was only runnin on three cylinders but thisone has had a compression test and all four are firin. but what prop should i order. i do have a workin tach and get about 3800 rpm WOT i am not sure what the max reccommended rpm is. thanks

Re: New Dash
 

Do some lookin' around to find out what Max RPMs you should be able to turn...it's KEY to makin' sure you got the right prop...


If motor change took you from 6 cyl to 4 cyl a prop change could most likely be in order...less torque, less hp?...need to know ;) :) ...

Re: New Dash
 

ok i will do that

just out of curisoty what would you guys think if someone put nitrus oxcide on their engine i saw it in the boating magazene it was an old issue (july 2002) but what would that do to an i/0 ses it adds 100 hp and 10mpg.

p.s. i dont like this new engine and am probable going to replace it next season. the engine is ecanomical ( spelling *???) but not very powerful i like power and *do not really care about economy kind of like comparing a hybrid to a hemi *i would much rather have the hemi.

Re: New Dash
 

on my 165 I/O I was getting 5000 rpm's!! You are way down!!
Some I/O get 4500 rpm but you have a way to go!! something wrong with motor??

You getting full throttle?? Or you need new prop??

Re: New Dash
 

The N O won't do ya much good w/ out the right prop, there, Hot Rod... ;) ;D ;D ...

Re: New Dash
 

what prop would you guys reccommend

Re: New Dash
 

On my boat I use a 15 1/4 X 15 it has a lot of torque and works well for me.

Do you have a Hydrofoil on the motor?? That helps alot!!

Are you sure you are getting full throttle?? Make sure of that first.

My mariner alowed me to talk to them, then they recomended a prop, they let me try, if no good and still perfect they would swap for the next size till I got what I wanted. I used 3 props.

Over all a 14 1/2 X 17 worked, but I always felt like I was spinning my tires when getting out the hole.

Thats when we found the 15 and now out the he great!! little slower on the top end, I use o get 40- 43 mph now I get 36-40 depending on the load.

Re: New Dash
 

If you had OB, I'd take a stab at it, but an I/O


HEY GUYS!!...another thing ??? ...any gear-reduction issues goin' on here...his outdrive originally w/ a 6 cyl...now has 4 cyl...any gearing goin' on in his outdrive ??? ...

Re: New Dash
 

That might be it!! My outdrive was from a V8 and I had to have the gears changed for stright 6cly.

Re: New Dash
