20" 150ho or 200 20"evinrude

[micel]

I have a custom 19' kevlar bay boat and want max performance.Should I get the ho lower unit or go for the extra horsepower?Thanks for imput!

Re: 20" 150ho or 200 20"evinrude

That's a loaded question. What hull design is it? Pad bottom with a step? What's your target speed?

Re: 20" 150ho or 200 20"evinrude

Thanks for the help,transom has a horazontal 15" inset and a vertical 6" drop to keel.The boat is 19.5' loa, 96"beam and weighs 1200 dry w/o engine.I am also contemplating a jackplate.As for a target speed while in ocean is 45 mph tops but a calm day in the bay i enjoy 50tt mph.Thats just it ,the fuel economy seems to stay the same after the boat gets on plane with the ho lower unit,where the regular unit gets progressively worse mpg the faster you go!

Re: 20" 150ho or 200 20"evinrude

Ok, it's a stepped hull. Does it have a pad? What's your expected speed?

What brand is it?

Re: 20" 150ho or 200 20"evinrude

No it does not have a pad like a bass boat,its got a rounded v (19 degree)keel although it is flat where the step is.Im getting 57mph w/22" 3blade w/200hp susuki(480lbs).Im happy with top end but would like better economy and raise stern up a little!

Re: 20" 150ho or 200 20"evinrude

By "raise the stern up" does that mean the bow will carry pretty easy with little positive (up) trim?

Re: 20" 150ho or 200 20"evinrude

That's my whole issue,I had the same hull 13 yrs ago with a 380lb 2.0 merc on it . Now with a 480lb suzuki the stern feels like its sucking to the water,even w/bobs manual convertible plate(suzuki has a 25 shaft to where the merc was rigged w/20") .The boat is a kevlar inshore cc,alot of the new manufactures call the transom/keel set-up a pocket drive.I loved the boat with the merc,but it handles like a different boat now.I think the Suzi has enough power(202 dyno and the plate is raising shaft up 5" and only setting it back 2.5") Something is not right.Before when the boat hit 400rpm it would like break loose from water, now I do not get that feeling at all.I'm not sure what prop I had before but now I have a 14.25x22'Thanks for input Michael

I would like to have the performance of my old boat, basically the only difference is weight of engine(80lb total).What do I need to do ?The new 2.6 evinrude would bring me to with in 30 lbs of original merc and be a 20" shaft!

Re: 20" 150ho or 200 20"evinrude

There's a world of difference between a 2 liter Merc and a Suzuki. You already know the set up is wrong with the Suzi and I'll bet the Merc had a better prop. You're not comparing apples to apples. Especially comparing either of these motors to a new E-Tec.

Re: 20" 150ho or 200 20"evinrude

I do not know what I was thinking writing 400tt(rpm or what) in post #7.What I meant was the boat acts as if it is glued to the water at 40mph. When I had the Merc on the boat it would like break loose and gain 10-20 mph without any effort.I am not trying to compare these four engines, its that I can only purchase the 20" 150ho new at the time and I was looking for a opinion on what would perform like the old merc did.From my memory the prop was some nasty 3 blade, which appeared to be aluminum.The 130hp carbed merc on the same boat appeared to run 55 mph all day and use very little fuel and handled like a dream! The Suzuki fuel and oil injected boat sucked the fuel will do 43mph w/22" prop handled terribly even w/a blue printed hull.I think if this post does anything,is that it proves how importantly a properly rigged boat is and that it is very,very hard to get it right on the money!I think that is what makes these forums so valuable! With todays epa regulations we are paying a huge weight penalty on outboard engines to meet todays epa standardizations.I see so many new boats rigged from the dealer so poorly, I true fully wonder how they can sell them.One of the quickest and best places to get your boat properly rigged is right here on iboats or similar forums!Its definitely a talent.

Re: 20" 150ho or 200 20"evinrude

your problem is the suzuki is a 25" shaft. even with the jack plate you are still running too low. the boat is designed with a pocket drive. pocket drives are made so you can mount the motor a bit higher "on the transom". the pocket drive allows the hump of water that comes off the back of the boat while on plane come out sooner so your prop is still in somewhat clean water while being mounted about 1/2" to 1" higher on the transom than on a non pocket drive.

by putting the jackplate on with a 25" motor you were able to run the 25" shaft motor but you are drowning your lower unit in the hump of water. being that it is a pocket drive the hump of water comes out sooner. your prop is actually in the position it would be at minimum lift with the correct 20" shaft motor you should be running. and i bet that 25" shaft is actually more like 26".

this is the reason you are feeling the drag feeling and not getting that loose sliding feel when turning. too much shaft in the water. if that 200 is pushing 200 to the prop with the correctt shaft length you would be flying!!

Re: 20" 150ho or 200 20"evinrude

I quess what I was wanting was wanting someone to tell me I will never get the performance out I want out of the Suzuki hence saving12k$.The Suzuki does not just not mess-up my speed and fuel economy, it also makes the boat handle terrible having the engine setting 5+ " higher and 2.5" back makes the boat very unstable at speed.Finding a nice Suzuki 20" 2-stroke mid- section is near impossible in s.e.FL.My delima now is which engine would best suit my boat, a 150h0 Rude or a 200 Rude of course in a 20" shaft or maybe another idea.Thanks

Re: 20" 150ho or 200 20"evinrude

with the 150 you should be at around 45mph if not faster at wot. if you want faster then go with the 200. i've never heard anyone say i want less power on my boat. i would stay within the max hp rating of the hull though.

Re: 20" 150ho or 200 20"evinrude

I have a coast guard certification that says 200hp(original tag was worn off).Gieco said that it could not be more than 10% of 150hp.Progressive did not say any thing about 200.My last reply I did not mean I wanted less power b/c evinrude does not really state hp for 150ho, plus ho has solid mounts and a hi-performance mid and lower unit.The 2.6 200 is basically a low power(190hp) run of mill e-tech.Also on the Suzuki the power is offset with weight(470+lb) and too long of shaft. If I could find a 20" suzuki shaft, it might be my cheapest alternative.In the last few years of trying to find a 20" suki shaft has only yielded complete running engines for 4000+$ .I dont know what to do after realizing how good it ran with the little merc on it. Running carbed 2.0 merc's are still bringing 3500+$. Thats why I am thinking of a 150ho or 200 e-tech,10000$, warranty,better fuel economy and greener.I have a hard time making expensive decisions and reading the internet one person states the e-techs have this issue and x brand has this issue.Thanks for the help Mike

Re: 20" 150ho or 200 20"evinrude

i can almost guarantee that any motor you get will have some kinda quirks in it. new or used. my buddy has a 200 e-tech and has had to change the fuel transfer pump 3 times(once a year basically). mechanic says he has been seeing them last about a year because of the ethanol in gas these days. he replaced the pump under warranty and told him to use a fuel stabilizer if he plans on letting gas sit in the tank for more than 2 weeks.

i know the merc optimax dfi ,motors have had there share of problems with sensors and what not. i do have a guy that does rebuilds and has a o hours rebuilt carburated 150 evinrude with low water pickup for sale currently. me and my buddies have bought a few motors from him and he always stands behind his products. he is in palm beach. here is a link to his ebay listing and you should check his ebay store. he is very honest and knows what he is doing especially on the omc motors. and he takes trade ins.

I think for your application ...the 150 h.o. would be the way to go. You'd have the high performance lower ( lightening case...I believe) with close to the hp of the 200 2.6 liter. The 200 has the magnum lower...which would not lend itself to high performance applications such as yours. And I'm not sure the 200 h.o. would be a viable option for you since the weight would be close to what you currently have.

Realistic choices would be the 150 h.o. or perhaps the Merc. 175 Pro XS.

Good Luck,

Wayne

Re: 20" 150ho or 200 20"evinrude

Thanks for input, so many models. A fellow fisherman took me out in a small mako cc with a df175, talking about refined, the wind makes more noise than engine underway. It even had torque that I thought was only possible with a 2-stroke. The weight is the only issue, its the same as I have now (470LBS) although literature states it has a offset drive shaft which sets the engine further forward to take some of the weight off stern.

Re: 20" 150ho or 200 20"evinrude

The offset is for a gear reduction. They couldn't get enough reduction in a case that size so they put gears under the powerhead.
