Yalta 555 owners: Urgent transom weight help required please

[quobbarockhopper]

Hi all

I have a 2005 model hull and am very close to signing up to repower it with a Yammi F150XL. I had/ have some concerns that the outboard may be too heavy for the transom. I have seen previous a previous thread on this site that the maximum weight rating is 190Kg and the Yammi comes in at 228kg, probably around 232kg with hydrolic steering fitted.


My compliance plate (situated just above the transom) says a max horsepower rating of 150, but doesn't specify a weight. In light of this, I called and followed up in a email with Yaltacraft directly, who informed me, in writing, that the max recommended weight was 220kg.

I guess what I would really appreciate peoples advice on is:

- (this may be a stupid question) Is there another compliance plate on the Yaltas that Im not aware of that states the weight?


- Mine is a 2005 model hull- does anyone know if they have increased the weight rating on the 555s over time?

- Can anyone point me in the direction of of any documentation that states the maximum transom weight of the 555s? I cant seem to find anything, that's why I went direct to Yalta when trying to figure it out.

- Im thinking (hoping) that in terms of potential damage to the transom caused by the extra 10-12kgs the yammi weights above the (allegedly?) 220kg rating would be pretty minimal. any thoughts on if the extra 10-12 would really have much effect?

- In terms of insurance, if my compliance plate only states 150hp and no weight and the max weighting (190-220kg?) info I was given only isn't written anywhere, I should not have a problem insurance wise if something was to go wrong?

Thanks a lot for any advice you could give me, it would be really appreciated and save me from a potential disaster, both boat and insurance wise! I need to make a decision in the next few days, and as you can probably tell, this is causing me a lot of indecision/ concern!

Cheers

Anthony,

In order to help you I would suggest that you follow up with Yalta Craft - chase George himself - and ask if he can help.

There are at least another couple active members on here that should help with info on their setups.
Cheers

I absolutely am a newbie and admit I know nothing worthwhile about boats, but I think Yaltacraft gave you the answer you are seeking.

Mate I had the 1800 alrounder and a 115 Yammi 2stroke and it did 43 knts so plenty of power maybe go the 115

Tried to reply to your PM mate, but your inbox is full. Here it is:

Heya mate, my Yalta is a 2006 model. Mine does have the weight on the transom on the compliance plate. It is in the splash well up near the two rod holders. Max HP 150 and Max weight 220KG.

So far there has been no issues with the transom, my engine weighs roughly 228KG as well. I have not noticed any cracks other then the gelcoat on the two supports you are talking about, but this is only gelcoat and I think it's more where the floor is joined at the rear.

I would have thought that a 115 on these hulls would make them kinda slugish resulting in a greater fuel burn. The 150 does not struggle at all getting on the plane. It also has enough grunt for bar crossings. Sitting on 3900 RPMs I can sit between 23 - 30knts depending on load and conditions. 3 blokes with a 140 liter esky full pulled 25knts in Morteon bay sitting on 4K. At 1770 between myself and hainesofast and two eskies full we were sitting on roughly 28knts doing 4K coming home from Fitzroy.

If you live in Brissy or Goldie, you're more then happy to come have a look. The boat ramp is only 20mins away too, so we could also take her for a cruise so you can see for yourself.

Just a thought, if the OP wants more than 115 horses and wants 4 stroke and the weight is a concern then why not look at another brand of outboard?

The Suzuki 140 weighs much less at 184kg for example.

[quobbarockhopper]

Jabiru... Yeah, I had (breifly) considered the 140 zuk, but theres no dealer/ servicer in my regional West Aust town for 500kms... so warranty servicing is the issue there? along with from the reading Ive done, the zuk 140 seems to be a fair bit less powerful than the Yam 150?

These are fighting words... haha Religous wars will begin!

From personal expereince, I went in a 5.5meter glass haines with a 140 05' zuke. It did feel like it had less power then the 150 Yammie and wasn't as response as a 150 which I didn't expect to see.

[myusernam]

what about the new naturally aspirated merc 150 ?

[ozynorts]

He currently has a Merc on the back that keeps breaking down so is a little off them at the moment....

You cant really tar completely different platforms with the same brush. I work for an OEM (not marine). We make systems by completely different factories and countries even, by engineers from different companies. Some are rebadged from other systems. Others are completely new designs from a fresh team. Every individual item is different. THe new merc 150 underwent a heap of R+D. They offer commercial guys in the states 5 years wty (instead of 1) . Check out the word around the place. looks like a very good thing.
