Hallo to everyone,
On my sun odyssey 42i I will install a maxpower bowthrust, I have no idea of the right engine I have to
buy: The CT 80 with 6.4 hp or the bigger CT100 with 9,5hp
There is somebody that have a jeanneau sun odyssey 42i 2007/2008 that have the bowthrust on board and can tell me the original choise of the french shipyard?
Thank's
Antonio

Write to Jeanneau Customer Services including the hull number of your 42DS and Jerome will tell you the answer. His English isn't so good but his customer service is excellent. Ian

What Jeanneau fits as standard and the reality of usage are sometimes two different things.
Go for the 100kg. As the 80kg on a 42ft boat with a flat belly like all newer Jeanneaus is a waste of money.
I have a SO40 with 80kg Maxpower and now wish I had the 100kg installed afterall.
Also, go for a good battery or batteries. I.e. one or two Optima Red Tops. You can use your anchor winch cables to charge them via your engine alternator, as long as u make sure to keep the anchor winch autofuse ON.

The Ct 80 has 69 kg thrust
The Ct 100 has 90 kg thrust
All the boat/ that I have see on 42/44 feet have a CT 80 max power bowthrust.
The Max Power CT 100 in fixed on the sun odyssey 49i

Well, fit a CT80 then "like all the other boats". Why ask!

dear friend Onyva, I ask to 42 owners with original bowthrust. If you write that you have a s.o.40 feet with Max power Ct 80 and you will have a ct100, you say something very incredibile: the ct 100 fitting on the 49 feets, you know the weigth ot this engine? 26 kg versus 15 kg of the ct 80, plus the batteries. If I ask 2/3 day ago, and now I know more details, I dont need your" if you know, why you ask" (  ??) Thanks for your reply. Antonio. |

Antonio, I am telling you the CT80 is just not powerfull enough, not even for my SO40. Hence I wished I had fitted the CT100 unit.
The standard fittings of Jeanneau where bow thrusters are concerned are too light in general. The 49i should have the next size up too. I have been part owner of a 49i with the Maxpower bowthruster as fitted by Jeanneau (CT100) and it was crap and useless with winds over 13 knots. Same for the SO54 DS, of which I have two in service management. Both useless bowthrusters in a bit of wind. All too light for the size and especially shape of the boat. With Beneteau´s the same story.
Don´t just look at what is fitted as "standard".
And that 9kg difference is not an issue on your size boat, nor the weight of the batteries.

Hello! I have a 42ds from 2011 and my bowtruster are a CT80. "Madicken of Sweden" Do you think your bowthrust is ok for the size of your boat, or you think you need a bigger engine with much more thrust? Thanks Antonio |

Antonio, i have a 42ds with the 80, is enough in normal conditions, is not enough up to 20 maybe 25 knods.
The weight difference with the 100 is big, the external dimensions are more or less the same.
now the ball is in your field
cheers!

Hello Antonio!
I think Spritz are right. If it´s up to 20 knots in the side 80 is ok. over 20 knots it´s to too weak. but below 20 knots the 100 is to heavy. And over 30 knots I think even 100 is too weak. It is a difficult decision. What do you prioritize? Weight, economy or to simply leave port in really strong winds.
Good luck with your decision, it is never easy .....

CT80 is OK on my 42DS in normal conditions.
CCA is more important than 1 or 2 batteries or capacity in Ah.
Get something like Redtop as mentioned earlier. I think mine is around 900 A CCA.

Hello,
There is more around the bow thruster - a battery bank placed very close to it is quite important and useful in the same time - and YES the cables for the anchor windlass can be used for charging.. but this is in case you intend to use this bank only for the bow thruster ... which is not very useful... in my case I have 3 x batteries near to the bow thruster all decoupled with diodes for charging and additional battery bank to the household using a powerful 6 diode , 2 x red + 2 x black 16mm2 ( 170amps) cable connecting this bank to the main switch and to the original bank and to the charging ( I decided in my case to not use the cables of the windlass as I want a stable independent system) this way you can still use your battery meter and it will work properly and you are safe from risk if one battery dies all batteries to day too ( as in the original battery bank connection from the manufacturer)
if interested let me know I will point you to the schematics cables, diodes etc. - total cost of properly done parts about £230 for cables and 30 for 2 x 6 diodes

Hi Vasco,
That sounds like a well thought out way of doing things. But for specifically a bow thrusther you want high CCA batteries (like Optima Red Tops or Excide Spirals) and not service batteries and vice versa.
What type of batteries have u installed there? As that bit of info was failing in your comments. And also, how many Amps of (service) battery power you have in total now on your boat?

My boat is quite small Liberty 34 but and originally was with 1x 72AH starter and 1x72AH household in the startboard locker...
I managed to install 1 x 88AH starter ( deep cycle - I decided to go for deepcycle no matter that for starter usually should be a starter battery as I got all batteries in the same deal and no probs so far) and for the house hold 1 x 88ah + 3 X125ah ( under teh bow bed) - my engine alternator is 60ah which is OK as the minimum ration shuld be 1/10 from the total baterry bank.
no matter that the boat is 34 foot I managed to fit - MaxPower BowThruster , 80E Katadyn watermaker & UV filter, 10 000 BTU aircon , 300W solars and 400W wind turbine and the fride si making real ice - the total costs for the whole solar kit was about £300 and £300 for the wind turbine - this includes the hybride controller and installed all myself.
Originally I got a local engineer ( my boat is in alicante) to do the thruster & the batteries, but the cabling was awful and no blocking diodes- I discover all when I put a NASA Battery Monitor and it was impossible to get it working correctly because of the lamer cabling installation ... and in the end I needed to redo the cabling myself , got cables , clamps and all tools and 1 days hard work and voala now all works like a charm...

Vasco: but now you can only take food for 2 days!!  Amazing you fitted all that in a 34ft boat. |

You think that just one Optima red top 50ah 1000cca will be enought for the Max Power CT80 bowthruster?
Thanks again,
Antonio

Have a 42I,agree with the negative comments about the power. Its good to 10/15 knots. Have replaced the 55ah redtop every season after it died due to emergency use.(Voltage alarm screaming) The 45 ft sun od. on the same pier as we are has the same problems, although he has 2 55ah redtops. Consulted battery experts. Have now 225ah deepcycle traction battery. No more alarms and no practical limitations to truster use. Moved the electrics around on the mutiplexboard, placed the battery aft of the trustermotor and secured with highend loadstraps, used two 2by4 beams to get the flex out the multiplexboard. Better to have a stronger truster too, but it stops somewhere. |

ok thanks,
how many cc has your 225 amp deep cycle battery? Max power recommend 900 cc amp..
